Welcome to OPIC 2022

Shuji Sakabe

Chair
OPIC 2022 Organizing Committee
Professor Emeritus, Kyoto University

Fumihiko Kannari

Chair
OPIC 2022 Steering Committee
Professor, Keio University

The Optics and Photonics International Council (Japan) has organized the Optics and Photonics International
Congress (OPIC) and the Optics and Photonics International Exhibition (OPIE) annually at Pacifico Yokohama since2012. OPIC historically includes more than 10 technical conferences in related technology areas. It is extremely importantto hold different optics-related technical conferences at one place at the same time because laser sources, light detection,and light active control are common elemental technologies. Sharing the supply and demand from each technicalconference accelerates the development of these technologies and their applications. OPIC is now one of the largest
international conferences suitable to efficiently attract the latest advanced science and technology information of optics,
photonics, and their applications.
However, due to the world-wide spreading of the new coronavirus (COVID-19), the last OPIC 2020 and 2021were notheld as an in-person conference, but as an online virtual conference. In spite of the online format, 11 technical professional
conferences were held, with 421 (2020) and 879 (2021) participants and 490 (2020) and 484 (2021) contributed papers. It
shows the significance of this congress and renewed our awareness that this annual congress should never be interrupted.
Though the coronavirus has not subsided perfectly even after two years, considering the sedation of virus infection
and the significance of this congress, we have decided to hold OPIC 2022 as a hybrid event – a combination of in-person
and virtual participation options. As a matter of course, we are prioritizing the safety and health of the participants at thecongress.
The OPIE 2022 exhibition will also be held at the same time for the first time in two years and we are expecting theactive flow of participants between OPIE 2022 and OPIC 2022.
OPIC 2022 is co-chaired by Yoshiaki Kato (Professor Emeritus, Osaka University), Christopher P. J. Barty (Universityof California, Irvine), Reinhart Poprawe (Senior Advisor Fraunhofer Gesellschaft, Chair for Lasertechnology RWTH
Aachen), and Ruxin Li (Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences).
OPIC 2022 is composed of 15 technical professional conferences, covering the fields of advanced lasers and photon
sources (ALPS), high energy density science (HEDS), nano-photonics and nano-optoelectronics (ICNN), information
photonics (IP), laser display and lighting (LDC), light-emitting devices and their industrial applications (LEDIA), tiny
integrated laser and laser ignition (LIC), laser and synchrotron radiation combination experiment (LSC), laser solutions
for space and the earth (LSSE), optical manipulation and structured materials (OMC), optical technology and measurement
for industrial applications (OPTM), optical wireless and fiber power transmission (OWPT), sensing and imaging throughscattering and fluctuation field in biology, telecommunication, and astronomy (SI-Thru), smart laser processing (SLPC),
and x-ray optics and applications (XOPT).
Each technical professional conference arranges its own unique hybrid scheme to combine some face-to-face lectures,
remote authors, and poster presentations, so please see the website of each technical professional conference for details.
The OPIC 2022 plenary session will be held at 9:00-12:00 on Wednesday 20th April. Three prominent scientists areinvited to give the plenary lectures: Dr. Tammy Ma (Lawrence Livermore National Laboratory, USA), Prof. Irina Sorokina(NTNU Norwegian University of Science and Technology, Norway) and Dr. Wentao Wang (Shanghai Institute of Optics
and Fine Mechanics, China).
The organizer would like to thank everyone who submitted a paper, as well as the invited speakers who agreed to makepresentations at OPIC 2022. We have made every effort to make this congress useful to all participants, so we hope you willfind OPIC 2022 fruitful and that it will strengthen our communication in spite of this difficult situation.
The OPI Council sincerely appreciates the authorized support of the Ministry of Education, Culture, Sports, Scienceand Technology (MEXT), the Ministry of Economy, Trade and Industry (METI), the Ministry of Health, Labour andWelfare (WHLW), the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), and Keidanren (Japan Business
Federation), Japan Science and Technology Agency (JST), New Energy and Industrial Technology Development
Organization (NEDO). We appreciate cooperation with the societies and agencies in Japan, USA, Germany, China, Taiwan,
and Korea. Also, we would like to thank the funding organizations and companies for their strong support of OPIC 2022.
The organizers hope that we will get together again in OPIC 2022 and celebrate overcoming the virus infection.

Welcome to the 11th Laser Display and Lighting Conference, LDC 2022!
LDC is an international conference on laser displays, laser lighting, and related technologies. The 1st LDC was held in Yokohama,Japan in 2012. After that, LDCs were held in Yokohama, Japan (2013, 2015, 2017~2019), in Taichung, Taiwan (2014), and in Jena,
Germany (2016). The 9th and 10th LDC were intended to be held in Yokohama, Japan, and switched to be on-line conferences owing
to the COVID-19 situation. The 11th LDC, LDC 2022 is being held as a hybrid-style on-line conference from 19th to 22nd April 2022.
LDC 2022 is sponsored by the Optical Society of Japan, in cooperation with several academic societies and associations, and is operated
by the Laser Display Research Group, the Optical Society of Japan.
LDC 2022 is intended to provide a central forum for the update and review of scientific and technical information on laser display
and lighting covering a wide range of fields from fundamental research to systems and applications.
A total of 40 papers will be presented during the 4-day conference, consisting of 2 keynote talks, 21 invited papers, and 17 contributed
papers. It is notable that number of submissions has grown compared to the last year, which is due to the kind interest and great support
from the LDC community against the consequences of COVID-19 in these years. A few post-deadline papers may be accepted.
In LDC 2022, two special sessions focusing on advanced AR/MR/VR/XR technologies will be held on 20th and 21st April, where
we will have stimulating invited talks from 6 expert speakers. An exciting special session entitled ‘Laser Applications for Automotive’

Conference Chair Hiroki Wadati
University of Hyogo
We are pleased to welcome you to the Conference on Laser and Synchrotron Radiation Combination Experiment(LSC) 2022.
As part of the OPTICS & PHOTONICS International Congress (OPIC), LSC aims to converge all scientists andengineers who are working on laser and synchrotron experiments all over the world.
The conference features invited talks and presentations on the recent developments, activities, and trends in lasers andsynchrotron sources, instrumentation, experimental techniques, and applications. Especially we will focus on the rapid
development of new experimental techniques such as ultrashort pulse lasers and X-ray free electron lasers, which made thestudy of sub-picosecond dynamics more accessible. A breakthrough, which has not been possible just by studying static
properties of materials, is expected to occur by studying sub-picosecond dynamics. Given the current state of this research
field, cooperation between laser and synchrotron is getting more and more important. We hope that you will find all the
LSC and OPIC activities interesting, engaging, and beneficial. We are very grateful for your participation, and we hope you
will have great time at the conference.

The 9th Optical Manipulation and Structured Materials
Conference OMC 2022

Conference

Co-sponsored by

SPIE.

Conference Chair Takashige Omatsu
Chiba University, Japan
Since the first demonstration of an optical tweezer based on optical radiation forces (scattering and gradient forces)
created by a tightly focused laser beam, optical tweezers have been widely investigated in a variety of research fields,
including biology, physics, and chemistry.
Conventional optical tweezers have been mostly adopted to dielectric particles with a wide dimension range fromhundreds of nanometers to tens of micrometers. However, they do not always enable us to efficiently trap nanoscale-sizedparticles.
In recent years, plasmonic tweezers based on enhanced radiation forces owing to surface plasmon polaritons inmetallic nanostructures have been proposed, and they offer the trapping and manipulating of both nanoscale-sized
dielectric and metallic particles. Also, non-plasmonic/non-thermal trap of numerous nanoscale-sized particles at highdensity has been demonstrated by employing a black silicon/titanium with nanoscale-sized needle-shaped structures.
Structured light fields, such as higher order Laguerre-Gaussian and Bessel beams carry orbital angular momentum,
and they provide unique tweezing abilities, for instance, of inducing an orbital motion of the trapped particles without
employing mechanical systems. They enable a range of exotic physical phenomena, in which structured light fields withorbital angular momentum can physically twist materials to form helical structures on nano-/micron-scale through theinteraction between orbital angular momentum and matters. It is worth mentioning that one of the most exciting
technologies, which may benefit from the use of structured light fields, is laser-induced forward transfer technology as a
non-contact printing technology.
Since 2014, the Optical Manipulation and Structured Materials Conference (OMC) has regularly collected more than
80 participants and more than 60 papers from domestic and abroad. The 9th OMC conference (OMC 2022) will be heldin Pacifico Yokohama at a hybrid format, and it aims to present and discuss up-to-date scientific subjects, new technologies,
and applications related to the fields of optical and plasmonic (non-plasmonic) tweezers, the manipulation of nanostructures,
structured optical fields, and their satellite topics.
We hope that this conference will also facilitate scientific and professional networking as well as scientific inspiration
through discussions.

This is the 4th conference of OPTM (Optical Technology and Measurement for Industrial Applications
Conference) since 2019. More than 20 presentations is expected in this year by the hybrid session connecting
the world. Although the restrictions of COVIDF-19 infection control is still strict, the OPTM activities
appear to be working very well thanks to participant enthusiasm.
The aim of the OPTM 2022 is to provide an international opportunity for introducing up-to-datetechnology in the filed of optical measurement and their applications for industries, at the same time, providing a networking opportunity
among young researchers and students is another important role of the conference. Also in the venue, other optics related exhibitions
and conferences will be hold, which will be a good chance to foster interest in different technical fields. We hope your visit to port of
Yokohama will be a nice experience in your technical and research carrier.

Dear colleagues,
As we are approaching the third OPIC congress under COVID-19 restrictions, I remember well our
optimistic spirit of last year. Many of us, including myself, were confident that the end of the pandemia
would come soon and that we would be able to meet face to face again in 2022. We also were anticipating asubstantial growth especially of our quite young conference “Optical Technology and Measurement for
Industrial Applications” OPTM with an increase in the number of presentations.
However, we have to face the fact that the pandemia is still here, OPTM again has to be performed in a hybrid format and probably
for this reason the number of presentations is smaller than a year before. I admit to having been disappointed about that for a while. But
taking a closer look at the submissions was lifting my spirits again. The abstracts are of excellent quality and they cover a large field of
methods and applications from medical diagnostics to manufacturing, from ellipsometry to interferometry, from finite element method
to neural networks. This is really showing the wealth and power of optics! Furthermore, presentations will be given by speakers from 8
coun-tries, spreading over 17 time zones of the earth.
After all, there is good reason to be optimistic again that OPTM has the potential to flourish and that next year we hopefully will
have overcome the pandemia and will be able to meet in the beautiful city Yokohama.
Enjoy the conference – either in presence or at your computer screen!

We are delighted to have the 4th conference on Optical Technology and Measurement for Industrial
Applications (OPTM) as part of OPIC 2022. These years we have been forced to persevere through difficult
times caused by natural (and sometimes human-made) disaster and especially coronavirus pandemic. Thisconference has potentially its origin in SPIE meetings and relates in any way to such concept as
optomechatronics that was originally born in Japan. Conventionally, research works are apt to be evaluatedhigher than practically applicative works. However, in addition to theoretical or analytical viewpoint, research should be also assessedfrom practical utility. In the near future, when we succeed in overcoming problems inherent to practical usage, we expect truly excellent
and useful result will be realized from the academic and practical viewpoint. Let’s enjoy this meeting and produce new result by
exchanging opinions freely and vigorously.

On behalf of the organizing committee and program committee, it is our great pleasure that the first conference of
Sensing and Imaging through Scattering and Fluctuating Fields in Biology, Telecommunications, and Astronomy (SIThru) within the framework of the OPTICS & PHOTONICS International Congress (OPIC 2022). Due to spreading of
COVID-19, the conference this year is performed as a hybrid conference of face-to-face in Pacifico Yokohama and online.
On behalf of the organizing committee and program committee, it is our great pleasure that the first conference of
Sensing and Imaging through Scattering and Fluctuating Fields in Biology, Telecommunications, and Astronomy (SIThru) within the framework of the OPTICS & PHOTONICS International Congress (OPIC 2022). Due to COVID-19, theconference this year is performed as a hybrid conference of face-to-face in Pacifico Yokohama and online.
Optics and related imaging techniques play indispensable roles in the development of natural sciences. However, there
remain problems that are not fully understood and overcome even with modern optical science and technologies. One ofsuch problems is the scattering and fluctuation. Recently, attractive approaches such as correlation-based approach withphase retrieval, and transmission matrix have been proposed to retrieve the original image from the scattered image.
Scattering and fluctuation phenomena can be seen in wide range from nanometer to kilometer order in 3D space. To tackle
this, we need to comprehensively measure the light scattered and fluctuated by multi-scale targets from living organisms
to the atmosphere, and utilize mathematical science and information science such as deep learning to understand thescattering and fluctuating fields. This will allow us clairvoyance; imaging of scattering and fluctuation themselves, as well
as objects behind them. Imaging through scattering and fluctuating fields brings innovations in natural sciences such as
life science and astronomy, and engineering such as information and communication technology. SI-Thru covers many
topics related to scattering and fluctuation.
Finally we hope the first SI-Thru contributes to the progress in this field and we hope you enjoy fruitful discussions in
the Conference.

Japan Laser Processing Society

SLPC 2022 Conference Chair Prof. Dr. Masahiro Tsukamoto
JWRI, Osaka University, JapanOn behalf of the organizing committee, it is our great pleasure to welcome you to SLPC 2022 - The 4th Smart Laser
Processing Conference which is organized by Japan Laser Processing Society (JLPS), Joining and Welding ResearchInstitute (JWRI) Osaka University, and OPI Council, Japan. Since 2014, the past SLPC conferences were launched withgenerous supports from many scientists and engineers in the fields of laser materials processing. Except SLPC2020 which
was cancelled due to the COVID-19, SLPC conferences were the great successes with the fine scientists and engineers
attending. And now, the 4th SLPC conference is held at PACIFICO Yokohama again to encourage rapid development oflaser processing technologies.
SLPC 2022 deals with science and technology of smart laser materials processing including micro- and macroprocessing. SLPC 2022 aims at providing a forum for discussion of fundamental aspects of laser-matter interaction, andthe state-of -the-art of smart laser processing, in addition to fostering next generation concepts and innovation bycollaboration among participants including scientists, end users and laser manufacturers. We wish smart laser processing
technologies also spread all over the world through this conference. SLPC 2022 is the 3-day event which consists of aplenary session, regular oral sessions, and poster session, collaborating with other 14 professional conferences in OPIC
2022 Optics & Photonics International Congress 2022. The conference site, Yokohama, is one of the famous port towns inJapan, and many technologies had been spread all countries in Japan through here. As you aware, SLPC 2022 is held as a
hybrid event this time - a combination of in-person and virtual online participation options. Considering the current
context of COVIE-19, there is no other way but to give lectures and participate in lectures by overseas residents, but inprinciple, we hope that the domestic residents give lectures and participate in a face-to-face manner.
We would like to express our sincere thanks to all the presenters, in particular the plenary and the invited speakers,
cooperating societies, media partners, and our sponsors. We would also like to thank the chairs and the members ofprogram committee, steering committee, international advisory committee, and the secretariat. Thank you very much forattending, and we sincerely hope you enjoy your time at the good season of fresh green leaves.

Femtosecond x-ray diffraction measurements
using XFEL were performed to study theliquid structure of tantalum shock-released
from several hundred GPa. Our results showthat the liquid tantalum at its shock-released
state sustains GPa class negative pressure.
This is the first direct evidence to prove theclassical nucleation theory which predicts
that liquid metals with high surface tension
can support GPa regime negative pressure.

In order to achieve high energy gain withlaser fusion, the fusion fuel must becompressed to the ultra-high density of morethan 1000 times the solid density. A solid
sphere is proposed as a novel fuel shape forthe fast ignition scheme, which does not
require the formation of a fusion igniter by
adiabatic compression. This talk will present
experimental results of high-density plasmacompression using three-stage sphericallyconverging shock waves.

A phase transition from zircon to thehigh-pressure reidite phase and a partial
melting were observed. The melt
recrystallized into zircon and reidite on

We design the experimental device togenerate scalar vortex beams of different
orders through the faithful reconstruction ofpolarization holography. The main advantageof this method is that the signal wave in therecording stage is not the generated vortex
beam; the reconstructed wave is the vortex
beam obtained in the reconstruction stage,
which varies from the vortex beams
produced by holography, where the signal
wave is already a vortex beam.

wavelength of excitation laser. The
simultaneous irradiation with excitation andnear-infrared lasers increased the averagetransit time of quantum-dot nanoparticles at
the focal spot, which depended on the power
and the wavelength of the excitation laser.
This suggests that the particle motion isconstrained due to optical trapping enhancedwith the resonant optical response.

Sustained pain can be caused byinflammation or injury. However, the neuralcircuit mechanism of sustained pain is
unknown. To reveal neural activity, we haveadapted a holographic microscope to a pain
model mouse. We found that increases insynchronized neural activity with highconnectivity in somatosensory cortex (S1).
These findings indicated that neural activity

several fatty acids biosynthesis mutants andsuccessfully developed new cultivars.

Juergen Czarske
Technishe Universitat Dresden
Coherent fiber bundles (CFB) enableultra-thin lensless endoscopes, but sufferfrom very strong aberrations that lead to
speckle patterns. Currently, spatial light
modulators (SLM) are used for digital opticalphase conjugation, which allows 3D imaging
without distal optics. However, the alignment
efforts are challenging. We present novel
diffractive optical elements (DOE) for
aberration correction and imaging. DOEs canbe printed directly onto the fiber facet by
2-photon lithography to correct static phase
distortions and allow 3D imaging andaberration correction without SLM. In
addition, random DOEs (scatter discs) can
encode 3D object information in 2D intensity
speckle patterns that are decoded usingneural networks (U-Net). Both approaches
enable single-shot 3D imaging in a compact
and robust system with diameters below
400 µm for applications such as aircraft
maintenance, casting, metal machining andespecially for biomedicine with stimulationsin optogenetics, monitoring for cochlea
implants and minimally invasive deep brain
imaging with keyhole access.

toward the source is always higher intensityand faster decay in contrast to the opposite
direction. This asymmetry can be explainedby the flux term in the framework of the
