The Optics and Photonics International Council (OPI Council) has held the Optics and Photonics International
Conference (OPIC) and the Optics and Photonics International Exhibition (OPIE) every year since 2012 at Pacifico
Yokohama in Japan. OPIC hosts more than 10 specialized international conferences (SICs) each year, with new SICs
added and the number of participants increasing each year. In the wide field of optics and photonics, it is importantthat various application developments are shared in one place and information is exchanged with each other,
centering on common core technologies such as optical materials including nonlinear optics, laser light sources,
photodetection, and optical active control. The main purpose of OPIC is to support the development of new academic
and applied fields by providing an efficient platform to support the organization of meetings for the exchange of
information among researchers, and promoting the development of emerging research. Since its founding in 2012,
OPIC has evolved into one of the largest international technical conference events, providing an efficient opportunity
for participants to interact on the latest advances in the science and technology of optics, photonics, and theirapplications.
Last year, OPIC 2023, which was positioned as the resumption of full-scale face-to-face conferences after the
COVID-19 pandemic, hosted 13 SICs and welcomed 1,067 participants from 49 countries. The number of papers
was 733. This confirmed once again that face-to-face technical exchange is a desirable format for researchers.
This year, OPIC 2024 consists of 16 SICs : Advanced Lasers and Photon Sources (ALPS); Business and Financein Sustainable Society (BFSS); Biomedical Imaging and Sensing (BISC); High Energy Density Science (HEDS);
Nano-photonics and Nano-optoelectronics (ICNN); Information Photonics (IP); Laser Displays and Lighting(LDC); Light-Emitting Devices and Their Industrial Applications (LEDIA); Laser and Synchrotron Combination
Experiments (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); Smart Laser Processing (SLPC); Tiny Integrated Lasers and Laser Ignition (TILALIC); X-ray Optics and Applications (XOPT). Each technical conference has a unique program of interesting
speakers, so we encourage registered attendees to attend presentations in multiple conferences. For more information,please visit each technical conference’s website.
The organizers would like to thank everyone who submitted papers and the invited speakers who agreed topresent their work at the meeting this year. We have made every effort to make this event beneficial to all participants,
and we hope that OPIC 2024 will be fruitful and improve our shared communication.

Numerical analysis was conducted to investigate
the impact of the various exciton and photon losses on
the laser threshold and slope efficiency by solving thelaser rate equations. Our findings indicate that thechange of exciton loss rate is proportional to the laser
threshold, while the slope efficiency remains unaffected.
Conversely, photon losses affect both the lasing
threshold and slope efficiency. The lasing threshold is
proportional to the photon loss and the slope efficiency
is inversely proportional to these losses.
Additionally, we explored the role of triplet excitonsin TADF-based organic lasers. Our results demonstratethat increasing the rate of reverse intersystem crossing
reduces triplet density, promoting laser emission
through reverse intersystem crossing and boosting
photon density. This process lowers the laser thresholdby using triplet excitons and mitigating triplet-related
losses.

Business and Finance in Sustainable Society 2024
-towards the expansion of photonics industry– BFSS 2024

ConferenceSponsored & Organized by

The Graduate School for the Creation of New Photonics Industries (GPI)
In corporation with

CAPITAL MARKET & WOMEN LAB (CAPW)

Conference Chair Rie H. Kang
The Graduate School for the Creation of New Photonics Industries, JapanThe aim of the conference is to integrate “Optics & Photonics technology with business” and “Optics & Photonics
technology with finance”. In recent years, participants in financial capital markets have moved closer to the field of scienceand technology more than ever before because of the movement towards sustainable finance, including ESG and impact
investment. However, universities and other research institutions with various technologies and university-launched startups and ventures have few opportunities to be aware of these financial capital markets. To accelerate the social
implementation and commercialization of university seeds, contact points with private business, and especially with thefinancial and capital markets that supply risk money, are indispensable.
Sustainable finance points out that thethree aspects of sustainable developmenteconomic, social, environmental- interact andit is important to choose the right combination.
Sustainable finance can be likened to the threestages of the ‘SDGs wedding cake’. As we allknow, ‘Optics & Photonics’ technology iscontributing to the resolution of issues related
to society and biosphere, as indicated in thisfigure. It is economic activities that linktechnologies such as energy, biotechnology,

laser processing and optical measurement tosocial implementation and commercialization

to create economic value. And it is SDGs No 17 ‘Partnership for the Goals’ that organically links these activities. The
Purpose of the BFSS is to realize this partnership.
Through this conference, we hope to explore new possibilities for ‘Optics & Photonics’ towards the realization of asustainable society by bringing together researchers, practitioners and financial and capital market players for exchange ofviews.

On behalf of the Organizing and Program Committees, we are delighted that the 10th Biomedical Imaging and Sensing
Conference will be held as part of the OPTICS & PHOTONICS International Congress (OPIC 2024).
In biomedical optics and photonics, optical tools are used to understand and treatment of disease, from the cellularlevel to clinical applications. At the cellular level, high-precision laser applications allow the manipulation, operation or
stimulation of cells, even in living organisms or animals by using fluorescent protein and optogenetics. Optical microscopy
has been revolutionized by the development of a wide variety of fluorescent dye probes and methods to control their
excitation and fluorescence behavior. Various label-free imaging techniques, such as multiphoton microscopy, secondand third-harmonic generation methods, and Raman microscopy, are spreading into many biological and clinicalapplications. Optical coherence tomography continues to expand its clinical and preclinical applications with higher
resolution, faster speed, further miniaturization, and the creation of novel approaches that enable imaging of functional
information and tissue dynamics.
Biomedical imaging and sensing are the most rapidly advancing and expanding areas in optics and photonics.
Techniques developed in these areas could bring us great advances in physical, engineering and biological knowledge aswell as in optics and photonics technology. The aim of this conference is to cover several aspects, from the fundamental
studies at the cellular level to the clinical applications of various optical technologies.
Finally, we hope that the 10th Biomedical Imaging and Sensing Conference will contribute to the progress in this field
and wish you fruitful discussions.

Welcome to the 13th Laser Display and Lighting Conference, LDC 2024!
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, but switched to be on-line conferences owing to
the COVID-19 situation. The 11th LDC was held as a hybrid on-line and in-person conference in 2022. The 12th LDC was held in
Yokohama in-person. Then, LDC 2024 is also being held as an in-person conference in Yokohama from 23rd to 26th April 2024. LDC
2024 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 2024 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, 22 invited papers, and 16
contributed papers. Several papers will be also presented as posters. It is notable that number of submissions is almost the same with
before and during the COVID-19 pandemic, which is due to the kind interest and great support from the LDC community to recoverfrom the difficult situation caused by COVID-19. A few post-deadline papers may be accepted.
In LDC 2024, a special session focusing on advanced XR and Metaverse technologies will be held on the 24th, where we will havestimulating invited talks from expert speakers. An exciting special session entitled ‘Laser Applications for Moving Platforms’ will also
be held with a number of distinguished speakers on 26th April. In these special sessions, state-of-the-art visible laser technology for XR,
Metaverse and moving target applications, will be presented, and discussed. After all the technical sessions, a ceremony for the LDC Best
Paper Award and the LDC Student Award will be held for exceptional papers commended for their outstanding achievement.
We would like to extend our sincere thanks to all the presenters and participants of LDC 2024 for their contribution to the successof the conference.

Conference on Laser and Synchrotron Radiation Combination
Experiment 2024 LSC 2024

Institute of Laser Engineering, Osaka University

ConferenceSponsored byConference Chair Toshihiko Shimizu
Institute of Laser Engineering, Osaka University, JapanWe are pleased to welcome you to the Conference on Laser and Synchrotron Radiation Combination Experiment(LSC) 2024.
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. In recent years, interdisciplinary
research, in which lasers and synchrotron radiation are applied to fields with which they have had little involvement, has

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. In fact, Dr. A. Ashkin was awarded Nobel Prize in Physics, for contributing to apioneering work of optical manipulation, 2018.
Conventional optical tweezers have been mostly adopted to dielectric particles with a dimension range from hundredsof nanometers to tens of micrometers. However, they do not always enable us to efficiently trap metallic particles.
In recent years, plasmonic tweezers based on enhanced radiation forces owing to surface plasmon polaritons inmetallic nanostructures have been successfully demonstrated to efficiently trap and manipulate both nanosacle-sized
dielectric and metallic particles.
Also, structured lights, such as higher order Laguerre-Gaussian and Bessel beams carry orbital angular momentum,
and they provide unique tweezing abilities, for instance, for inducing an orbital motion of the trapped particles without
employing mechanical systems.
Since 2014, the OMC has successfully collected more than 80 participants from home and abroad, and it marked its
10th anniversary last year! The OMC 2024 conference aims to present and discuss up-to-date scientific subjects, newtechnologies, and applications related to the fields of optical and 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.

Conference Chair Takunori TairaRIKEN SPring-8 Center (RSC) / Institute for Molecular Science (IMS)
Welcome to the 10th Tiny Integrated Laser and Laser Ignition Conference 2024 (TILA-LIC 2024), which is theinternational forum for discussions on various aspects of the ubiquitous sources and phenomena associated with highly
intense laser pulses. TILA-LIC offers to share information on sciences and technologies related to Giant Micro-photonics.
“Tiny Integrated Laser (TILA)” means the compact integration of highly intense laser devices and peripheral systems thatenables ubiquitous operation of extraordinarily accurate measurements and control of extreme material phases. Here, theword “laser ignition (LI)” originally means the laser induced breakdown ignition, and it also implies the induction ofphenomena caused by the irradiation of high-brightness laser pulses until the TILA based material processing, laser driven
particle acceleration and the other intense laser applications. Based on the recent photonic innovation called by Giant
Micro-photonics, ubiquitous lasers symbolized by TILA that can be operated at everywhere and anytime by everybody can
become the door to promote the world to a new generation. The conference will be held at Pacifico Yokohama, Yokohama,Japan, on April 24-26, 2024 with the sponsorship from Laser-Driven Electron-Acceleration Technology Group, RIKEN
SPring-8 Center, and Division of Research Innovation and Collaboration, Institute for Molecular Science in cooperation
with several academic societies and associations.
After TILA-LIC opening talks, a total of 42+ papers will be presented, consisting of one Keynote, one Tutorial, twoPlenary, 12 Invited papers, and 26 Contributed papers. In addition, we organize 4 introduction talks with regarding the
TILA related company activity. At the closing remarks, award ceremony will be held at which several papers will becommended for their outstanding achievement. We would like to extend our thanks to all the presenters and participantsof TILA-LIC 2024 for their contribution to the success of the conference. We also express our thanks to the endorsement

The origin of energetic non-thermal particles
in the Universe is an open question.
Collisionless shocks [1-3], with theirassociated instabilities [4], can transfer
energy to particles during their interaction
with ambient plasma. Using high-power
lasers coupled with strong magnetic fields,
we can produce such shocks andinstabilities in the laboratory and observe
the energization of protons.

We propose a simple, scalable and compact
device for efficient generation of multiple
vector-vortex beams. The device is apolarization hologram fabricated on a azo
functionalized copolymer, using a simple
interferometric arrangement. Simply
illuminating the fabricated hologram with acollimated beam is enough to generate
multiple vector-vortex beams, without theneed for any additional optics.

The idea of burst pulses is to divide a highpulse energy into several individual pulses that
follow each other at short intervals (a few 10
ns up to a few 100 ps). Thus, each individual
pulse in the burst gets closer to the optimal
fluence associated with a maximal conversionof the pulse energy. Compared to a processwith high-energy single pulses, the processwith burst pulses becomes significantly more
efficient at the same laser repetition rate.

uses the light beams reflected on both
surfaces of a sample under measurementand doesn’t use the light beams transmitted
through the sample. The expanded
uncertainty of silicon wafer thickness

A Stokes camera can display the spatial
distribution of Stokes parameters S0-S3, but
resolution is an issue when capturing finepolarization states. To evaluate the resolutionof the camera, we evaluate the degree ofcontrast loss with increasing spatial
frequency. The spatial distribution of S1 in
the form of stripes is generated by aninterferometer, and the contrast is calculated
by varying the spacing between the stripes.

The emission and polarization control ofterahertz waves is important in wide
applications. Here, with a pulsed
femtosecond laser split into a main-pulse
and two pre-pulses, an advanced finecontrol of THz emission is achieved.

The aim of this paper is to investigate
potential benefits of using a high-speed
laser (10 kHz) to ignite and stabilize a liquid
fuel flames by directly igniting droplets.
Plasma is formed in droplets crossing thelaser beam, not only at the focal point of thebeam, leading to multiple ignition spots. The
effects of laser frequency as well as laser
energy is investigated for various injection
parameters.

The focus of this presentation is on using
artificial intelligence algorithms to “make theinvisible visible”. We will discuss howclassified, physical properties can be derived
from already reliable process information.
Rather than defining complex rules foralgorithms, the use of Data Science andMachine Learning methods reveals hidden
structures in noisy unstructured data andmake it possible to find the relationships ofthe data to the physical measurement.

Density dependence of positron
acceleration by longitudinal electricfield in relativistic laser-plasmainteraction
Kaoru Sugimoto
Yuakawa Institute for Theoretical Physics,
Kyoto University
We performed 2D PIC simulation ofinteraction between an ultra-intense laser
light and a near critical density plasma. It
has been observed that e –-e+ pair creation
happened due to photon collisions. Some ofthe positrons are accelerated by alongitudinal electric field induced by acharge separation at the laser pulse front.
The positrons are energized to near GeV
level. We also confirmed that positron
acceleration can be caused by initial target
density 0.5-5.6nc.

Fast decay emission from cross-luminescence(CL) in wide band gap fluoride crystals are in
the vacuum ultraviolet (VUV) wavelength
region. The ability to shift VUV luminescence
to UV will enable easier detection of the fast
emission. Uniform volume compression
through hydrostatic high-pressure
applications decreases the energy gap
between the valence and core bands of KMgF
and BaF crystals, potentially shifting their CL
emission from 200nm (VUV) to 300nm (UV).

Recently laser-generated whistler waves
have attracted attention because they
enable direct heating of high-density
plasmas. We have investigated its
characteristics by kinetic simulations up to
date. As a result, we have found that strong
stimulated Brillouin scattering inhibits thewhistler wave propagation and therefore
transmitted pulse duration is limited.

In an OWPT system, the position, andattitude of the photovoltaic device should betracked from the light source. The authors
proposed a robust PV detection, positioning,
and attitude determination method using a
differential absorption image combined withthe stereo imagery technique. This study
reports the achievements of its successive

Takuto Mizutani, Tomoyuki Miyamoto
Tokyo Institute of Technology
The IoT utilizes a vast number of terminals,
and OWPT as a power supply method will
become the most important method forstable continuous operation of all terminals.
For efficient configuration operation of thesystem, numerical simulations was reperformed for establishment of a power
supply order algorithm. As a result, many

We propose one-dimensional digitalholography for a shape measurement of an
object that is moving laterally with a known

intensity detection and calculation. The
repetition of the digital holography is higher
than that of the ordinary two-dimensional

We propose an optical manipulation method
to selectively target a particular emission
line by using the recoil force generated
when irradiating materials with induced lightunder their inverted-occupation conditions.
We evaluated this force using a four-levelsystem and performed a kinetic analysis todemonstrate emission-line selective
manipulation.

Thermal expansion coefficients of YAG
ceramics doped with Nd3+, Yb3+, Er3+, Sm3+,
and Cr4+ ions were evaluated from -150 °C
to 700 °C. Measured thermal expansion
coefficient of various kinds of YAG ceramics
were coincided to Nd:YAG single crystals,
and no significant differences depending on
dopants were detected.

We demonstrate an experimental procedure
based on a repetitive and sub-microsecond
switching of the trapping laser intensity
which leads to the squeezing of the phasespace probability density distribution of thelevitated nanoparticle in vacuum.

The local inhomogeneity of crystals used forlaser oscillation influences the laser damage
resistance and it may mislead us aboutmaterials evaluation. We consideredevaluation methods for crystals having local
inhomogeneity and applied experimental
data.
