Message from OITDA

Yasuhisa Odani
President/Vice Chairman
Optoelectronics Industry and Technology
Development Association (OITDA)

We are pleased to present here a technical information report summarizing the surveys and R&D activities conducted by
OITDA in FY2022.
First, let us look at the overall trends in the optoelectronics industry from the FY2022 survey. The total shipment value ofthe optoelectronics industry increased from +0.3% in FY2021 to +8.5% in FY2022, totaling 12,643 billion yen, while thedomestic production value increased significantly from -0.2% in FY2021 to +6.2% in FY2022, totaling 6,206 billion yen.
Most of the fields are expanding, with the Optical Input/Output field expanding by +23.5%, a remarkable increase due to therise of image sensors, surveillance and vehicle-mounted cameras, and mirrorless single-lens digital cameras. The OpticalCommunications field has increased by +10.4% and has grown annually for the past four years due to the surge in information
traffic. The Sensing/Measurement field has also increased by +8.7% and has grown for the fifth year in a row due to a rise indemand for IoT and other applications. The Laser/Optical Processing field rebounded significantly, up +23.5% in FY2021
and +10.0% in FY2022. The Photovoltaic Energy field has grown by +3.8%.
Next, I would like to introduce some items of special note for FY2022, while detailed activities and results of individual
projects by OITDA in FY2022 can be found in the rest of this report.
We established a special committee under the Technology Strategy Development Committee to create a “Technology
Roadmap for Applying Visible Light Semiconductor Lasers to Achieve Carbon Neutrality" in anticipation of demand for
new applications. These include integrated systems of displays, lighting, and indoor visible light communications, longdistance visible light communications, blue laser processing, and agricultural applications. The results of these were presented
at the Symposium on the Optoelectronics Industry and Technology held on February 8, 2023.
In the area of standardization, we used projects commissioned by the Ministry of Economy, Trade and Industry (METI)
to promote projects that include the development of evaluation technologies for international standards, such as for multicore
fiber optical connectors, automotive Ethernet systems, and optical disks for archiving. The last two themes were successfullycompleted, thus achieving our initial goals. In addition, we actively participated in international standardization by the IEC,
ISO, and in various forums, including ISO/TC 172/SC 9, and IEC/TC 76, which serve as the domestic secretariat. Furthermore,
for the first time in three years, we were able to hold a laser safety school and laser equipment handling technician exams
in a face-to-face setting.
For the feasibility study project, we conducted leading research and strategic planning surveys on two themes: Integrated
LIDAR Sensors for Air Mobility and Market Development of Optical Wireless Power Transmission Systems for Small
Mobile Devices.
In terms of technological development, the project for High-Efficiency, High-Speed Processing Distributed Computing
System Using Heterogeneous Material Integrated Optoelectronics, which was launched in FY2021 as a NEDO commissioned
project based on leading research conducted by OITDA, is being implemented at the Photonics Electronics Technology
Research Association (PETRA). Another project conducted based on our leading research is the Research and Developmentof High Speed and Low Power Data Transfer System Using Photonic & Electronic Hybrid Switch, which reached its final
year in FY2022. Efforts are now underway to put spatial switches and burst-capable optical digital coherent transceivers,
which were developed as a result of this project, into practical use.
The OITDA is promoting the development of R&D and commercialization strategies, including the above-mentioned
technologies, as the cornerstone of industry-academia-government collaboration related to optoelectronic industrial technology.
We are also implementing projects in FY2023 on key issues related to optoelectronic industrial technology. These issues
include surveys and research, promotion of technological development, and promotion of standardization. Under the directionof METI and other government agencies, we are committed to enhancing and strengthening our business activities to meetthe needs of our members, with the cooperation and understanding of many people in industry, including supporting members,
and academia, an important partner.
We wish you good health and look forward to your continued guidance, support, and cooperation.

Display/Solid-state Lighting field and Photovoltaic Energy field.

OITDA has conducted the “Survey of Trends of the Optoelectronics
Industry” annually since its foundation in 1980. The accumulated survey
data of more than 40 years is highly regarded as the basic source fortrends of the Japanese optoelectronics industry.
This year, we have set seven research subcommittees under the“Optoelectronic Industry Trends Investigation Committee” and conducteda survey for the statistical data from FY 2021 to FY 2023, including theshipment value and domestic production value of the entire Japanese
optoelectronic industry.

2. 	Total Shipments and Domestic Production for the
Optoelectronics Industry
2.1 Survey Method
We conducted a questionnaire survey of the domestic companies
producing optical-related products (optical equipment/systems andcomponents) on the results of FY2021 (actual), FY2022 (estimate), andFY2023 (qualitative prediction) for total shipments (including overseas
production) and domestic production. The questionnaires were sent to201 companies in October 2022 and collected between December 2022
and February 2023. Responses were obtained from 82 companies.
Regarding the prediction for the next fiscal year, a quantitative survey
had been conducted until FY2010, but the accuracy and reliability was
not sufficient thereafter. Therefore, it has changed to a qualitative survey
since FY2011. Specifically, the evaluation was made on a five-point
scale: increase, little increase, flat, little decrease, and decrease, comparedto the previous year.
We received the cooperation of the Japan Photovoltaic Energy
Association (JPEA) for the Photovoltaic field, the Japan Lighting
Manufacturers Association (JLMA) for the Solid-state Lighting field,
the Japan Electronics and Information Technology Industries Association(JEITA) for the Display field, and the Imaging Products Association(CIPA) /Fuji Chimera Research Institute Inc. for the Input/Output field.
Based on the survey, we have compiled the total shipments anddomestic production in the optical industry in Japan as a whole byconducting data validity examinations and industrial trend analysis byeach specialized subcommittee for each product field, and theOptoelectronic Industry Trends Investigation Committee has rechecked
the validity of the data and analysis results.
For the survey, we classified the optoelectronics industry, together
with relevant optical equipment/systems and components, into the sevenfields shown below.
1. OpticalCommunication:

Optoelectronics Industry Trends
semiconductor and automotive industries, the total shipments anddomestic production in the Laser/Optical Processing field increased
significantly, while those in the Sensing/Measuring field increased
modestly, primarily for optical sensing equipment. In the Display/Solidstate Lighting field, both total shipments and domestic production
increased marginally. This is due to a rebound in LED lighting
equipment, which showed a decline in FY2020, and an increase indemand for display devices, which have consistently shown negative
growth, fueled by 5G terminals and other products. In the OpticalCommunications field, optical fiber and optical connectors performed
well against the backdrop of increased demand for 5G systems and data
centers, while optical devices declined due to supply shortages ofsemiconductor devices and other components, levelling total shipments
and domestic production. Demand for consumer use in the Optical
Storage field continued to decline, as did total shipments and domestic
production. Due to shortages in supply of power semiconductors andother devices, the Photovoltaic Energy field experienced a decline inboth total shipments and domestic production. The optoelectronics
Industry as a whole shows a recovering trend, but total shipment anddomestic production were flat due to a number of factors, such ascomponent supply shortages caused by the spread of COVID-19.
Overall, total shipments for the optoelectronics industry totaled 11,650
billion yen with -0.3% growth rate, while domestic production totaled
5,842 billion yen with a -0.2% growth rate.
●FY 2022 (estimate)In the Input/Output field, both total shipments and domestic production
are expected to increase significantly due to increased demand for image
sensors for automotive and other applications, mirrorless single-lensdigital cameras with higher prices, and printers and MFPs for satellite
offices and other uses. Both total shipments and domestic productionin the Laser/Optical Processing field are expected to rise in tandem withrising capital expenditures, especially in the semiconductor andautomotive industries. In the Sensing/Measurement field, both total
shipments and domestic production are expected to show a somewhat
modest increase, similar to the previous year. The Optical Storage field
is expected to show an increase in total shipments and domestic
production due to increased demand for playback-only equipment forgame consoles. The Photovoltaic Energy field is also expected to see
an increase in total shipments and domestic production due to thestrengthening of policies to expand the introduction of photovoltaic
power generation and the trend to prevent prices from falling. In the
Optical Communications field, in addition to an increase in demand for5G systems and data centers, the supply shortage of components suchas semiconductors will be resolved, leading in an increase in both total
shipments and domestic production. Optical transmission equipment
and devices will also see higher demand, as well as optical fibers andother components. In the Display/Solid-state Lighting field, flat panel
displays and LED lighting equipment will perform well, whereas display
devices will decline, and as a whole, both total shipments and domestic
production are expected to remain unchanged. In the optoelectronics
industry as a whole, both total shipments and domestic production are
expected to increase as the effects of component supply shortages andother factors subside.
The total shipment value of the optoelectronics industry is expected
to reach 12,643 billion yen, an 8.5% growth rate, and the domestic
production value is expected to reach 6,206 billion yen, a 6.2% positive
growth rate.
●FY 2023 (prediction)
Due to a rise in demand for image sensors, imaging equipment, andprinters/multifunction devices, our prediction for the Input/Output fieldindicate a slight increase in total shipments and a flat domestic
production. In the Laser/Optical Processing and Sensing/Measurement

composition ratio: 20.8%), 736 billion yen for the Laser/Optical
Processing field (growth rate: 23.2%; composition ratio: 12.6%), and238 billion yen for the Sensing/Measuring field (growth rate: 14.6%;
composition ratio: 4.1%).
●FY 2022 (estimate): 6,206 billion yen, growth rate: 6.2%
The domestic production of the optoelectronics industry in FY2022
is estimated to be 6,206 billion yen (growth rate: 6.2%). This breaks
down as 3,716 billion yen for optoelectronics equipment/systems (growth
rate: 8.2%; composition ratio: 59.9%) and 2,490 billion yen for opticalcomponents (growth rate: 3.4%; composition ratio: 40.1%).
The domestic productions by fields were 456 billion yen for the
Optical Communication field (growth rate: 11.7%; composition ratio:7.3%), 26 billion yen for the Optical Storage field (growth rate: 15.5%;composition ratio: 0.4%), 1,217 billion yen for the I/O field (growth
rate: 25.3%; composition ratio: 19.6%), 2,077 billion yen for the Display/
Solid-state Lighting field (growth rate:-4.0%; composition ratio: 33.5%), 1,265 billion yen for the Photovoltaic
Energy field (growth rate: 4.1%; composition ratio: 20.4%), 813 billion
yen for the Laser/Optical Processing field (growth rate: 10.4%;
composition ratio: 13.1%), and 257 billion yen for the Sensing/Measuring
field (growth rate: 7.6%; composition ratio: 4.1%).
●FY 2023 (prediction): flat
The domestic production of the optoelectronic industry in FY2023
is expected to be flat. Likewise, the production for optical equipment/
systems and optical components are also expected to be flat.
The expectations for production values are as follows:
little increase for Optical Storage field, Display/Solid-state Lighting
field, Laser/Optical Processing field and Sensing/Measuring field; flat
for Optical Communication field, I/O field and Photovoltaic Energy
field.
2.4 Trend in Optoelectronics Industry
Figures 1 and 2 show changes in the total shipment value of theoptoelectronics industry and trends in each field, respectively. Figures
3 and 4 show changes in the domestic production value of theoptoelectronics industry and changes by field, respectively. Figure 1
and 3 also show nominal GDP and electronic industry production inorder to compare changes in the scale of the optoelectronics industry
with those of the Japanese economy and other industries.
Japanʼs optoelectronic industry has continued to grow for a long periodof more than 20 years since the survey started in FY1980, although there
was a temporary decline due to the burst of the dot-com bubble.
However, it became negative due to the impact of the financial crisis in
FY2008. In addition, the tough situation continued due to the impact of
the Great East Japan Earthquake in FY2011. After that, it turned to bepositive due to the rapid growth in the Photovoltaic Energy field.
However, after peaking in FY2014, the Photovoltaic Energy field showeda significant downward trend, and the production of the entire
optoelectronic industry decreased in FY2015 and FY2016 for the second
consecutive year. In FY2017, it was expected to be almost flat andbottom out, but the downward trend continued after FY2018.
Moreover, in FY2020, the optoelectronic industry suffered great damage
due to the COVID-19 pandemic.
In FY2021, there was an overall recovery trend, and in FY2022, it isexpected that there will be positive growth.
The following is a summary of the survey results of this year andanalysis for financial year.
●FY2021 (actual)
In the Input/Output field, products such as image sensors and imaging
equipment recovered partly because of a rebound from FY2020, resulting
in a significant increase in both total shipments and domestic production.
Owing to a recovery in capital investments, primarily in the3

fields, both total shipments and domestic production are projected toincrease slightly due to capital investment, mainly in the semiconductor
and automotive industries. Our forecast for the Optical Communications
field indicates that total shipments and domestic production will remainunchanged as investments related to 5G systems and data centers
continue. In the Optical Storage field, demand for playback-only
equipment for game consoles is expected to continue, with total
shipments forecast to remain flat. In Display/Solid-state Lighting, LED
lighting equipment is strong, but due to a lack of forward-looking factors
in other areas, we forecast that all shipments will be flat while domestic
production will increase marginally. In the Photovoltaic Energy field,
both total shipments and domestic production are forecast to be flat as
the policy to expand installations continues. In the optoelectronics
industry as a whole, both total shipments and domestic production are
forecast to be flat.

Technological Strategy Development
1. Introduction

technology, have become already a reality, and display products suchas laser televisions, portable laser projectors, and head-up displays are
now in widespread use. In the future, based on the evolution ofsemiconductor lasers (improved conversion efficiency and single-chip
integration), Laser Displays are expected to advance by acquiring further
features and functionality such as reduced energy consumption, AR/VR
applications, and functional fusion (integrated multi-functionality), while
adapting to both super-smart society and carbon neutrality.

OITDA has been developing Optical Technology Roadmap annually
since 1996 with the aim of identifying the future growth of theoptoelectronics industry and directing the research and development of
optical technologies.
This activity has made sweeping contributions to the development of theoptoelectronics industry, laying the groundwork for a multitude of national
projects in the fields of data communications, data recording, displays,
optical energy, and optical processing. Since FY2016, the goal of strategy
formulation has been to determine how optical technology can contributeto specific application fields, rather than by each technological field, androadmaps had been compiled based on keywords such as automobiles &mobility, AI and IoT, Beyond 5G, imaging, and cyber physical society.
For FY2022, we developed a roadmap for the visible lightsemiconductor laser technology essential for multiple use cases under thetitle, Visible Light Semiconductor Laser Technology for Carbon Neutrality.
The use cases include adaptation to an ultra-smart society that employs
visible light semiconductor lasers, and their agricultural applications.

(3) Visible Light Communications
Visible Light Communications are characterized by their ultra-low
power consumption and scalability, which allow for communications
on land, sea, air, and space, where radio waves cannot or are difficult
to communicate. LiFi is an indispensable communication method due
to its low power consumption and high data transfer rate. By repurposing
LED and Laser Lighting implemented in society as communications
devices, LiFi can realize an ultra-smart society and reduced power
consumption. To utilize semiconductor lasers in these areas, it is crucial
to boost the efficiency, responsiveness, and output power of lasers. In
addition, the ultraviolet and visible light spectrums require thedevelopment of highly sensitive GaN-based PIN diodes.

2. Optical technology roadmap
Recent years have witnessed the research and development of new
applications for visible light semiconductor lasers. At the same time,
visible light semiconductor lasers are becoming more efficient andpowerful, and their oscillation wavelength range is expanding, which
will likely lead to the development of promising new applications. The
development of applications employing visible semiconductor lasers
will probably help resolve social issues we will face in the near future,such as a super-aging society, a declining working population due to afalling birthrate, the advent of a super-information society, and a decline
in food self-sufficiency and a decrease in the number of agricultural
workers. In addition, the increased use of high-performance visible
semiconductor lasers is projected to reduce CO2 emissions byapproximately 63 million tons in 2040 compared to current levels. The
FY2022 roadmap identifies future visions for six application fields
employing visible semiconductor lasers and outlines a roadmap for thetechnological fields necessary to realize these visions.

(4) Laser Assisted Agriculture
Global population growth through 2040 will increase the demand forfood. Due to increased global climate change in the natural environment,
there is concern that agricultural output will become unstable. For
institutional cultivation, which is less susceptible to environmental
factors, an alternative light source to sunlight is required. We should
acquire multi-wavelength and High Efficiency technologies for visible
light lasers by around 2030 and should apply them not only toinstitutional cultivation but also to open field cultivation, which accounts
for the majority of the world's cultivation, by 2040. Although lightsources of the whole wavelength must be available to grow plants inthe same manner as sunlight, plants can be cultivated by combining
multiple wavelengths. Moreover, the use of short-wavelength light canbe effective in preventing disease. This is applicable not only to disease
control during crop management, but also to the reduction of spoilagerelated waste during transport and storage. The advancement ofsemiconductor lasers can expand Laser Assisted Agriculture in the future.

2.1 Application areas(1) Laser Lighting
Recently, LEDs have surpassed other light sources by a wide margin
in terms of efficiency and lifespan, and have become the norm for indoor
lighting. Using semiconductor lasers in place of LEDs for illumination
affords lighting with unique and superior properties that leverage the highdirectivity, that is, the extremely high luminance, of the emitted light.
The high luminance of the light emitted by semiconductor lasers alsoenables multicolor and a wider color gamut. Since the ultimate wide
color gamut can be achieved by adding yellow light (Y) to RGB, it isnecessary to develop and enhance the efficiency of yellow semiconductor
lasers in addition to RGB ones. The integration of Laser Lighting withvital sensing, display, and communications (LiFi) will probably
contribute to a society with greater convenience.

(5) Optical Wireless Power Transmission
Optical Wireless Power Transmission offers the following features:no wiring is required; devices can be made compact; power can besupplied over long distances; there is no risk of electric shock; and power
can be supplied between transparent, light-penetrable objects. Thesefeatures open up a variety of possible applications, including thepowering of household appliances, drones, electric vehicles, robots, andindustrial devices and systems, as well as power transmission
infrastructure alternative to wires. We envision the possibility of theapplications expanding from the powering of robots and other devices
in indoor areas where human access is restricted, to that of electricvehicles (EV) and other devices outdoors, as well as infrastructure
applications. Accordingly, the supplied power will need to be higher,
and the lasers will need to have higher efficiency and greater output
power. We envisage the need for higher performance VCSELs, PCSELs,
and MQS-LDs as long-distance power transmission requires high beam
quality. We envision that after achieving greater responsivity in theviolet wavelength range, photodetectors will undergo development forunderwater use and higher performance. We also envision that powertransmission systems will see the development of essential elemental
technologies such as tracking, and achieve longer transmission distances
as safety systems become more advanced.

(2) Laser Displays
The research and development of Laser Displays began in the 1960s
with He-Ne monochromatic laser televisions produced by Texas
Instruments. It accelerated in the 21st century due to the remarkabledevelopment of laser light sources, including the commercialization of
GaN-based pure blue semiconductor lasers. Semiconductor lasers havesignificant advantages over other light sources in terms of color
reproduction, polarization, directivity, small emission area, and highbrightness. Thanks to the recent remarkable progress of laser lightsources, color Laser Displays, which were once thought to be a dream9

2022 OITDA

single blue laser diode and 3.7% wall plug efficiency (WPE) for a green
one. In addition, 256-channel blue VCSEL in a two-dimensional array isreported to have an output of 1.19 W. It is expected that in the future,
increased efficiency and multiple channels will lead to higher output.
PCSELs are capable of single-mode oscillation over a large area witha diameter of several hundred µm and are characterized by high output
power and narrow divergence angle. Progress is being made in thedevelopment of PCSELs of infrared light, with some reported to operate
at approximately 7 W, and design guidelines for the 100 W to 1 kW
power range have been presented. It has been reported that blue PCSELs
have an output of at least 1 W and a divergence angle of approximately
0.2°, and they will probably achieve higher power in the future.
MQS-LD use a nanowire structure. They have an increased active
layer volume due to the height of their quantum shell structure and canbe arranged to afford a large overlap of in-plane standing waves with
the quantum shell active layer. Thereby, they can increase the opticalconfinement factor, and may enable beam characteristics with high powerand high quality through the periodic arrangement of Multi Quantum
Shell (MQS).

(6) Laser Processing
Due to high electrical and thermal conductivity, copper products will
be utilized extensively in EVs, for which future demand is expected toincrease. Thus, blue semiconductor lasers have already started to be usedpractically in copper machining and are being actively used, particularly
in manufacturing processes related to batteries, motors, and inverters,
which are key components for EVs. Future concerns for high-power blue
semiconductor lasers include increasing power, improving beam quality,and decreasing price. As the power conversion efficiency of blue
semiconductor lasers increases in the future, the optical output and beam
quality of laser processing machines employing multiple blue
semiconductor lasers will be greatly improved, and a large number ofthese machines will be incorporated into the production of EVs and their
key components, such as batteries, motors, and inverters. This will probably
significantly reduce the cost of EVs with superior safety performance.

2.2 Technical Fields(1) High Efficiency
Laser devices must have a low threshold, low voltage, and high slope
efficiency in order to be highly efficient. Potential solutions to reducing
the threshold of GaN-based lasers include thicker active layers (welllayers), high-composition AlGaN cladding, thicker AlGaN cladding
layers, and high-composition InGaN guide layers. However, all thesesolutions have parameters that are in a trade-off relationship, so an
optimal balance between the parameters must be achieved in design toachieve high efficiency.

(6) Tracking
Realistically, tracking information can be acquired in two steps: byrecognizing the general direction with a GPS sensor, and then byswitching to an optical tracking sensor or a split light receiving device.
The optical tracking sensor consists of a wide-angle lens and CMOS
sensor, and the split light receiving device controls the azimuth so thatthe laser is incident equally on each device. In the case of Optical WirelessPower Transmission, adequate performance should be achievable if thetransmission method is chosen based on the transmission distance andthe speed of the moving object. As for scanners, existing technologies
such as Galvanometer scanners, MEMS scanners, and DLP chips can beutilized, and it is possible to track laser beams by making the appropriate
selections based on the required accuracy and scanning range.

(2) Multi-Colorization
Yellow and red, which have longer wavelengths than green, aredesirable for laser oscillation. However, the external quantum efficiency
of GaN-based lasers is known to decrease significantly at wavelengthsof 540 nm or longer, making it difficult to extend the wavelength ofGaN-based lasers.
In addition to usual methods for increasing the In and Al compositions,high-quality high-InGaN layers and longer wavelengths are being
researched. Such layers can be formed by reducing the stress from thesubstrate and underlying layers for the high In-composition active layer
required for longer wavelengths, and wavelengths can be increased with
In concentration, using the properties of cubic GaN.

(7) Interlocking with Sensing
In visible laser applications, Interlocking with Sensing will beessential. Visible laser application systems must incorporate twodimensional spatial information, distance information, and alignment
with laser irradiation optics for application to semiconductor lasers.
LiDAR is well-suited for collecting these types of information.
If the development of higher-resolution visible light color LiDAR
advances, it will be possible to combine LiDAR, camera, and illumination
into a single device, which can be regarded as the ultimate sensor device.
In the future, its applications will probably expand into various settings.
By integrating all functionality including illumination, display, spatial
optical communications, optical power transmission, and indication,
the visible light scanning system will not only have LiDAR functionality,
but it will also be applicable to visible light laser systems, such as IoT
lighting stations with multiple functions.

(3) High Power
Increasing the power of semiconductor lasers presents numerous obstacles
that must be overcome. Achieving high efficiency will help in achieving
high output power by improving the issue of thermal saturation of the optical
output caused by heat generation. To increase the output power of current
edge-emitting lasers, it is necessary to reduce self-heating, enhance highheat-dissipation mounts, prevent facet breakdown, and enhance facet coating
films. Moreover, surface-emitting lasers, such as VCSELs and PCSELs,
can achieve greater output power by expanding the emission area.

3. Summary(4) Laser Spreading Angle Control
Recently, PCSELs and MQS-LD have been introduced as
semiconductor lasers with new structures. Since PCSELs emit laser
light perpendicular to the semiconductor substrate, increasing their device
surface area can significantly increase output without incurring opticaldamage. The device presented as a MQS-LD is an edge-emitting device,
but by forming the resonator vertically, it can also function as a VCSEL.
Therefore, like a PCSEL, it can generate a high-quality beam with aconsiderably high output, using a single element.

GaN-based blue semiconductor lasers still have significant room fordevelopment, with the possibility of increasing output by introducing
window structures and other designs and decreasing series resistanceby introducing tunnel junctions. As such, the early demonstration of
those technologies being used to achieve energy efficiencies that surpass
that of LEDs will expand realistic expectations for visible lightsemiconductor lasers. At the same time, we should promote a national
project for industry-academia collaboration at an early stage to improve
the properties of new semiconductor lasers that have high potential,
such as VCSELs, PCSELs, and MQS-LDs, and lead the world in thedevelopment of demonstration models for the six application fields.

(5) VCSEL,PCSEL,MQS-LD, and Arrays
VCSELs have a reported power conversion efficiency of 13.6% for a

1. Introduction

manufacturers of the same type of products, which makes standardization
efforts extremely important. This committee harmonizes JIS andcorresponding IEC international standards for optical connectors inaccordance with WTO/TBT agreements that came into effect in 1995.

Standardization has been one of OITDAʼs major activities since its
establishment and has been promoted across the optoelectronics industry.
Our standardization efforts are mainly focused on optical transmission,and also include several fiber optics applications and lasers. Our activities
cover not just domestic standardization (Japanese Industrial Standards(JIS)), but also international standardization such as IEC and ISO. We
also establish and revise OITDA standards and OITDA Technical Papers(TP) to complement obsolete JIS and to serve as literature forinternational proposals. These standardization efforts are based on
ongoing studies by field-specific committees focused on the need foradapting to a changing industrial structure. Outlined below are theactivities of each field-specific committee.

5. Optical Passive Device Standardization Committee
This committee is responsible for various tasks such as drafting new
JIS proposals and revising existing ones pertaining to optical passive
components. Additionally, the committee conducts reviews andinvestigations on general regulations, testing, and measuringmethodologies, and individual specifications for optical passive
components. The committee also investigates international
standardization trends in this field.

2. Fiber Optics Standardization Committee

6. Optical Active Device Standardization Committee

The Fiber Optics Standardization Committee was established to steer
standardization activities for fiber optics. It also serves as the planningand promotion arm of the OITDA Standardization Society General
Committee, while coordinating the consistency and overall direction of
all standardization activities. It established two acting subcommittees
under its wing, the Administrative Advisory Subcommittee and the IntraBuilding Optical Wiring Subcommittee.
In FY2022, the committee focused on resolving problems anddeveloping strategies in JIS and international standardization. In addition,it has made great strides in promoting standardization of OITDA
standards and TPs, which were studied and introduced by this committee
to complement JIS and international standards.

The general approach of this committee is to develop JIS harmonizedwith the IEC standards framework.
Currently, the IEC formulates standards for optical active components
while envisioning the emergence of new optical transmission systems.
These include wavelength division multiplexing passive optical networks(WDM-PON), digital coherent transmission, ultrahigh-speed LAN, andspace division multiplexing (SDM) optical transmission. In addition to
the standardization of individual components, discussions are also being
proposed and deliberated on the standardization of optical active
components as integrated functional devices. This standardization
includes performance and package standards for analog opticaltransceivers for mobile front haul and photonic integrated circuits (PICs).
The committee is gathering information about them to engage in its
activities.

2.1 Administrative Advisory Subcommittee
The Administrative Advisory Subcommittee actively promotes theenactment/revision of OITDA standards and TPs, which are organization
standards, in order to propose international standards and to back up
JIS standards. It continually identifies and resolves issues to facilitate
efficient standardization drafting. Its other duties include the investigationof issues common to each field-specific standardization committee, andcoordination with other organizations.

7. Optical Amplifier and Dynamic Module Standardization
Committee
The IECʼs decision to merge TC 86/SC 86C/WG 3 and WG 5 promoted
the consolidation of the Optical Amplifier Standardization Subcommittee,
the Fiber Optics Standardization Subcommittee, and the Dynamic
Module Subcommittee into the current Optical Amplifier and Dynamic
Module Standardization Committee for Japanʼs standardization activities.
The two main activities of this committee are (1) to prepare translationsof JIS drafts while taking into account IEC standardization deliberations
and national circumstances, and (2) to keep abreast of international
standardization trends and make proposals as appropriate via domestic
committees.

2.2 Intra-Building Optical Wiring Subcommittee
This subcommittee works on the standardization of optical wiring
systems for residents or housing providers of houses, apartments, andcommercial buildings to enable the use of high-speed, broadband data
and video services. Specifically, the subcommittee prepares materials
to disseminate and provide information on matters such as FTTH opticalwiring in buildings and relevant technological trends.

8. Optical Subsystem Standardization Committee
IEC/TC 86/SC 86C/WG 1 deals with standardization of the physicallayer of optical communication systems and subsystems, establishingdesign guidelines for optical systems and standardizing test methods
for optical systems (systems in general, digital systems, optical cabling
equipment and optical links). The committee has been supporting thestandardization efforts of SC 86C/WG 1, and has been working on thesequential JIS standardization of IEC standards that have already been
issued and for which there is a high need in Japan. In addition, to promote
more active proposals to the IEC for technologies in which Japan ismaking progress, the committee provides assistance in investigating
new technologies and preparing documents that contribute to thosestandardizations.

3. Optical Fiber Standardization Committee
This subcommittee deals with international standards related to opticalfiber. Specifically, it ensures harmony between various IEC and ITU-T
testing methods and product standards, and reviews JIS according to
the enactment and revision of international standards. It also captures

phase of this project (three years) was launched in FY2020, and FY2022
was the third year of this project. In addition to development of IEC,
ISO and IEEE standards, the project will advance the development ofevaluation methods for in-vehicle communication systems aiming at
system integrity and preparations for the establishment of testing andcertification bodies. Continuing from last year, the project developed atotal of 12 standards: 9 new, 2 continued/revised, and 1 revised. These
were mainly related to Multi-gigabit Ethernet.

In order to strengthen the efforts of IEC/TC 76/WG 5 (Safety of fibre
and free space optical communication systems), the OpticalCommunications Technical Subcommittee was established and carries
out activities under TC 76, Laser Safety Standardization Subcommittee.
In addition, the committee also collaborates with each of the following
groups: JTC 5 (JTC with IEC and CIE) for deliberations on IEC 624711; JWG 21 (JWG with IEC TC 34) for deliberations on IEC 62471-7;
applicable ISO committees in Japan for JWG 10 and JWG 12 projects
to deliberate joint standards with the ISO; and the IEC/TC 86/JAG 10
for matters related to optical fiber communications.

15. Optical Disk Archiving Grade Standardization Committee
Due to the rapid progress of the information explosion in recent years,
optical disks are expected to drive the creation of an archive market as
a strategic storage medium for digital data. Against this backdrop, thisproject has developed evaluation criteria for optical disk archive systems
based on physical standards and lifetime estimation standards for each
optical disk product (CD, DVD, BD, etc.) that have been established sofar. The evaluation criteria include a media grading system based on
the initial performance of the optical disk itself, and consistency withdrives to ensure the recording quality of digital data. Currently, in order
to expand the data storage infrastructure on a global scale, and strengthen
the international competitiveness of optical disk archiving systems andmedia, the committee is (1) revising JIS to incorporate new issues
identified through operation, and (2) expanding those standards tointernational standards.

11. ISO/TC 172/SC 9 Standardization Committee
In FY2022, regarding the deliberation of ISO documents, thiscommittee deliberated the documents circulated by each WG of the ISO
and proposed opinions from Japan. With regard to efforts for the ISO/TC 172/SC 9 international meeting, the committee sent experts to theannual meeting of SC 9 (held remotely) to reflect Japanese opinions on
international standard proposals.

12. Optical Disk Standardization Committee
The Optical Disk Standardization Committee is a standardizationgroup specializing in the standardization of optical disk-related
technologies. Its main activities include the drafting of domestic
standards, and research and study of related technology trends. It
established two subcommittees that conduct activities under its wing,
the Media Technical Subcommittee and Format Technical Subcommittee.

16. International Standardization Proposal Committee on
Optical Interoperability of Connectors for Multicore Fibers
In order to meet the ever-growing demand for communications, thepractical application of Space Division Multiplexing (SDM) technology
aiming at increasing transmission capacity has become an urgent issue.
A system using Multi-Core Fiber (MCF) has been developed as a method
to realize SDM technology, and an optical connector for MCF is
indispensable to realize this system. On the other hand, when used in
an optical network, standardization regarding optical interoperability,
which is necessary for performance assurance when optical connectorsof a plurality of manufacturers are connected to each other, is required.
Therefore, we aim to expand the market worldwide in the future throughthe rapid spread of new technologies for optical connectors for MCF,
which has been developed in Japan. This project is a three-year projectfrom 2021. At the IEC meeting, the technical presentation had been
made for the international standardization of optical connectors for MCF,
and a draft international standard for optical interoperability of opticalconnectors for MCF will be prepared. We propose it to IEC / TC 86 /SC 86B and work toward the target of registering it as an international
standard NP (New Work Item Proposal) by February 2024.

12.1 Optical Disk Media Sub-committee
This technical subcommittee conducts research and study activities
related to standardization of physical format standards, application
standards, and reliability evaluation standards for magneto-optical,
phase-change, write-once, and read-only optical disks.
12.2 Optical Disk Format Sub-committee
This technical subcommittee conducts research and study related tovolume and file formats for optical disks.

13. Fiber Optic Sensors Standardization Committee
This subcommittee was established as a technical subcommittee under
the former Fiber Optics Standardization Committee with the purposeof acting as a domestic committee (mirror committee) of IEC/TC 86/
SC 86C/WG 2. It reflects Japanese opinions in the preparation ofinternational standards and actively disseminates Japanese technologies
as international standards. The committee took its first step toward its
aspirations of creating JIS drafts by officially drafting JIS C 617575(corresponding international standard IEC 617575) in January 2022. In
April of the same year, it transitioned from a Technical Subcommittee
to a Standardization Committee. In February 2023, this JIS was publishedin the Official Gazette.

14. International Standard Development Committee for
In-vehicle Ethernet System Integrity
In-vehicle communications are expected to increase in capacity toallow for advanced driving assistance systems and automated driving.
In-vehicle Ethernet standards with enhanced real-time performance andfail-safe features require high reliability to serve as the communication
backbone and sensor network for connecting core units in autonomousvehicles. Particularly with regard to EMC, a reliable in-vehiclecommunication system can be achieved by combining a communication
board with excellent EMC characteristics and an optical harness thatneither generates nor is affected by electromagnetic noise. The fourth
