OPIC (Optics and Photonics International Congress) and OPIE (Optics and Photonics International
Exhibition) are the international forums to present and discuss the most up-to-date R&D and industrial
activities in optics and photonics in the world and to exchange thoughts on the role of optics and photonics in
our future society. The first OPIC/OPIE was started in 2012 under the organization of the Optics and Photonics
International Council (OPI Council) and has been held each year in Yokohama.
The Nobel Prize in Physics in 2018 was chosen from the laser science field deeply related to the OPIC
topics; Prof. Arthur Ashkin, for the optical tweezeres and their application to biological systems, and Profs.
Gerard Mourou and Donna Strickland, for their method of generating high-intensity, ultra-short optical pulses(chirped pulse amplification). Both have been contributing greatly to the fields of biology, chemistry andphysics. The communities related to this OPIC are pleased that the award winners come from the target fieldsof this congress. The OPIC organizer and participants will be delighted to celebrate the winning of the threeprofessors. At the beginning of the plenary session, Chris Barty (Congress chair) and Takeshige Omatsu (OMC
Chair) will give short presentations on the Nobel Prize Laureates.
At the plenary session of OPIC 2019, four distinguished speakers will present on the following hot topics;‘Recent advances in SESAM-modelocked high-power thin disk lasers’, ‘The 10 PW and 100 PW lasers: Paving
the way for exploring the next frontier of high field physics’, ‘A billion times brighter: An overview of therevolution underway in X-ray science’, and ‘Quantum neural network - coherent Ising machine, XY machineand recurrent neural network’.
OPIC 2019 is composed of 14 professional conferences. We are very pleased to welcome OPTM 2019
(Optical Technology and Measurement for Industrial Applications) and OWPT 2019 (Optical Wireless andFiber Power Transmission Conference) to OPIC this year.
The OPI Council sincerely appreciates the authorized support of the Ministry of Education, Culture, Sports,
Science and Technology (MEXT), the Ministry of Economics, Trade and Industry (METI), the Ministry ofAgriculture, Forest and Fishery (MAFF), the Ministry of Health, Labor and Welfare (WHLW), the Ministry ofLand, Infrastructure, Transport and Tourism (MLIT), and Keidanren (Japan Business Federation). We
appreciate cooperation with the societies and agencies in Japan, USA, Germany, Taiwan, and Korea. Also wewould like to thank the founding organizations and companies for their strong support of OPIC 2019.

For Dr. Arthur Ashkin

Greetings
Prof. Sadao Nakai

Osaka University, JapanWe are very glad to welcome you at the Optics andPhotonics International Congress, OPIC 2019. This is
the 8th OPIC, which has been growing held at the sameplace, Pacifico Yokohama, together with the OPIE,
exhibition, since the first one in 2012.
As you know, the basic five foundations of the modern
society are ① food supply, ② medicine and health care,③ manufacturing and construction, ④ information andartificial intelligence and ⑤ energy and environment. In
all these fields, optics, photonics and lasers have theessential role for developing the brand-new concept.
In OPIC 2019 of this year, 14 specialized conferences
have been organized, which will open the new world
with light and light-related science and technologies.
These conferences have been realized with the great
efforts of the respective conference chairs and theircollaborators. The conference names and thephotographs of the chairs are shown on the viewgraph.
I would like to deeply appreciate their dedications.
This year at OPIC 2019, we have the pleasure tocelebrate the Winners of the Novel Prize in Physics
2018: Drs. Arthur Ashkin, Gerard Mourou, and Donna
Strickland. Congratulations!! These Nobel Prize
Laureates are introduced by Prof. Chris Barty and Prof.
Takashige Omatsu.
We hope that all of you will get bright inspiration
and active information through close and friendly
contact each other during the Congress and Exhibition.
Please enjoy the beautiful Japan in this best season.

OPIC 2019・22-26 April, 2019

Prof. Takashige Omatsu
Chiba University, Japan

Dr. Arthur Ashkin should be called ‘the father of
optical radiation pressure’. He performed, for the firsttime, laser cooling of atoms and optical trapping ofatoms. In 1986, Ashkin also demonstrated, for the firsttime, optical trapping of micron-scale dielectric particles
by a single-beam gradient force trap, known as ‘opticaltweezers’. He extended his optical tweezers to trap andmanipulate living materials, such as bacteria, viruses, andcells. Nowadays, his optical tweezers pave the way towards
the understanding of normal and diseased states in thehuman body, and the elucidation of the mystery of life.
Ashkin was awarded many awards and honors
recognizing his scientific contributions, in particular,
the Nobel Prize in Physics for his work on opticaltrapping and manipulation in 2018.
I briefly introduce his outstanding achievements andrecent progresses in optical trapping and manipulation.

For Dr. Gerard Mourou& Dr. Donna Strickland
Prof. Christopher Barty
University of California,
Irvine, USA

2018 was a banner year for the Optics and Photonics
community with three individuals, Professors Arthur
Ashkin, Donna Strickland and Gérard Mourou, winning
the Nobel Prize in Physics for their pioneering contributions
to laser science and applications. With respect to the
Optics and Photonics International Congress, the award
to Professors Mourou and Strickland is particularly
significant. Professor Mourou has not only been a plenary
speaker at previous OPIC meetings but has also been theorganizer and/or inspiration for several of this congress’s
topical meetings. His and Donna Strickland’s inventionof chirped pulse amplification has had and continues tohave tremendous impact on both the science andapplications discussed at OPIC as well as the technologies
represented at the concurrent OPIE trade show. The OPIC
extends its congratulations to Gérard Mourou and Donna
Strickland and thanks them for their many contributions
to the success of the OPIC conference series.

‘A billion times brighter’: An overview of
the revolution underway in X-ray scienceradiation are: ultrashort pulse length (currently 0.2 to200 fs), high transverse coherence and controllable
longitudinal coherence, extreme brightness (typically 109

to scan wavelength (roughly 0.05 to 5 nm). As such,
XFELs are well suited to deploying a wide array ofimaging, scattering and spectroscopic tools for studying
the dynamics of matter at the molecular scale – providing
chemical specificity with atomic resolution, on thetimescales that molecular bonds are formed and evolve.

Abstract
The past decade has seen the emergence of X-ray Free
Electron Lasers (XFELs) as a powerful new tool forstudying the world at the atomic and molecular scale, withapplications to quantum materials, catalytic chemistry, thescience of extreme conditions, and structural biology.
These facilities provide ultrashort X-ray pulses with a peakbrilliance over 9 orders of magnitude higher thansynchrotron sources – allowing us to capture atomic level
detail on femtosecond timescales using a wide range of
coherent imaging and spectroscopy tools.
This field is now entering another step-change, withthe repetition rate of the sources increasing by manyorders of magnitude to provide high average power

Similar facilities have been commissioned in Japan(SACLA), Republic of Korea (PAL-FEL), Switzerland(Swiss-FEL), and Germany (European-XFEL). The
latter marks a step-change in capability, increasing therepetition rate to 27,000 Hz, thanks to a superconducting
linear accelerator.

Sponsored by

Conference

Conference Chair Toyohiko Yatagai
Center for Optical Research and Education, Utsunomiya University
On behalf of the organizing committee and program committee, it is our great pleasure that the 5-th Biomedical
Imaging and Sensing Conference in Yokohama is going to open successfully, within the framework of the OPTICS &PHOTONICS International Congress (OPIC 2019). In biomedical optics and photonics, optical tools are employed for theunderstanding and treatment of diseases, from the cellular level to macroscopic applications. At the cellular level, highly
precise laser applications allows the manipulation, operation or stimulation of cells, even in living organisms or animals.
Optical microscopy has been revolutionized by a thorough understanding of the different markers and their switching
behavior. Marker-free microscopy, like CARS, SHG or THG-microscopy is spreading into multiple biological and clinicalimaging applications. OCT is continuously broadening its clinical applicability by even higher resolution, higher speed
and more compact and the use of Doppler and polarization sensitivity for functional imaging.
In the field of optics and photonics, biomedical imaging and sensing areas are most quickly progressing and expanding.
Techniques developed in these areas could bring us great steps in advances of physical, engineering and biologicalknowledge as well as optics and photonics technology. This conference aims at covering several aspects from thefundamental studies at cellular level to clinical applications of various optical technologies.
Finally we hope the 5-th Biomedical Imaging and Sensing Conference contributes to the progress in this field and wehope you enjoy fruitful discussions in the Conference.

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 optical angular momenta, andthey 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. The OMC 2019conference aims to present and discuss up-to-date scientific subjects, new technologies, and applications related to thefields 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.

Laser Wakefield Acceleration (LWFA) has
potential to drastically reduce the size of
future particle accelerators. However, themaximum energy of the particles in a single
stage LWFA is limited by dephasing length.
To continuously boost the energy of theparticles multi-stage LWFA is necessary. The
main problem in the multi-stage LWFA is
coupling of beam charge in succesive
stages.We will discuss the limitations
caused by charge coupling.

The effect of pressure on the plasma
formation of dual-pulse laser-induced
breakdown (DPLIB) was studied in air atpressures of 1 bar and 10 bar and comparedto single-pulse laser-induced breakdown(SPLIB) of the same total energy. Both DPLIB
and SPLIB had a smaller breakdown size forincreased pressure. DPLIB was larger than
SPLIB and could potentially be more
beneficial for ignition than SPLIB at elevatedpressure conditions due to the increased
spark surface area.

A size minimization of the shaped beam has
attracted much attention, because it directly
connects to their performances in theapplications. In this paper, we demonstrated
a proximity-complex amplitude optimization
to minimize the size of the focused beam.
Furthermore, femtosecond laser processing
using the sub-diffraction-limit spot was
performed.

Huan Xiao, Qiaofeng Tan
Tsinghua University
The large-angle diffraction field obtained bya double-sampling diffractions calculation
algorithm has problems such as uneven lightintensity. We have obtained a good beam
shaping effect by optimizing the algorithm.
We also performed machining error analysis
on binary optics designed with optimized
algorithms.

to a commercial cameras. Experiments show
the distribution of diattenuation andorientation over all of the pixels of thecamera. Since the diattenuation values are
low, and the orientation varies frompixel-to-pixel, we also outline a method fortaking the calibration parameters andestimating the input polarization state.

We propose a method to calibrate thepachymetry for central corneal thickness(CCT) measurement from a Scheimpflug
imaging of a non-contact tonometer. Our
calibration method takes into account not
only the Scheimpflug imaging geometricdistortion but also the slit width variation of
the Scheimpflug illumination path. Based our
method, CCT measurement with accuracy
better than ±12 um is achieved.

Deflectometry is a powerful technique fortesting specular reflecting surfaces, even ofcomplex shape. It is used extensively inchecking e.g. painted car bodies for
irregularities and waviness. About 15 years
ago quantitative evaluation techniques havebeen developed and are now applied inindustry to measure the shape of strongly
aspheric or freeform optical surfaces, e.g.
reflectors for illumination systems or
progressive spectacle lenses. The
measurement setup in principle is quite
simple, but to get accurate results a deep
understanding of the measurement process
is required. And it is even more demanding
to estimate the error budgets and themeasurement uncertainty. In ourpresentation we will give a survey ofclassical deflectometry and discuss theinfluence of the cameras and the flat screen
used for generating the reference patterns.

Whispering gallery mode (WGM) is proposed
for microsphere diameter measurement. In
order to get the mode number of a WGM, amethod of using a SNOM probe to measure
the near-field light of WGM on microspheresurface is proposed. Then in order to verify
the disturbance of the SNOM probe on WGM

In this paper, we present the payload
portability of power-over-fiber (PWoF) drones
for airborne base stations (ABSs) using Siand GaAs-based photovoltaic power
converters (PPCs). Based on the supply
power per weight of the PPCs and the
take-off weight of drones, it is found that
GaAs-based PPC is more suitable for using
PWoF drones. Moreover, we show the
relationship between the take-off weight andthe required supply power for practical use
as ABSs.

The integral floating display is a technique toenhance the parameters of an integral
imaging three-dimensional display byadopting a floating lens on it. The previous
analyses on the integral floating display
were based on an assumption of a floatinglens with an infinite aperture and presented
an ideal viewing region only. In this paper,

plane and reconstructed back 3D image.
Light field data, however, has a limitation in
depth-recording. A light field display

on a flat display. It consists of a lens array
and a flat display. Problem is that visual

The dynamics of the PW class laser pulses
in overdense plasmas is investigated via two
and three - dimensional particle-in-cellsimulation. It was found that the laser pulse
propagates through the overdense plasma
by combination of hole boring and relativistictransparency. During pulse propagation,strong backward Raman scattering withfrequency drop and strong forward Raman
scattering with frequency rise are observed.

In applications of neutrons for radiograph,neutron flux is a key issue so that highly
directional neutron generation has beenrequired. In photonuclear reaction with
deuterium and X-ray, the direction of neutron
generation can be controlled by nuclear spinof the deuterium and polarization of the

Phase analysis of light carrying optical Design of high-FOV automatic opticalvortex for refractive index sensing
inspection lens for linear sensor withdifferent magnification
Youngbin Na, Do-Kyeong Ko
Gwangju Institute of Science and Technology
We present a highly sensitive refractive
index (RI) sensor based on a phase analysis
of light beam carrying an optical vortex.
Because the phase of the vortex is
proportional to the spatial azimuth angle, we
can estimate the RI of a sample bymeasuring the rotated angle. As a proof ofconcept, we calculate the rotated angle ofthe vortex according to the concentration of
aqueous solutions and investigate changes
in resolution and dynamic range overdifferent path lengths.

we analysis the diffraction pattern SNR thatwas design by IFTA. The diffraction pattern
directly affected the system resolution.
Therefore, we design the two types ofdiffraction pattern by IFTA and compare theimaging quality. From the simulation result,
we found the circular pattern which Signal toNoise Ratio was 1.5 times to the rectangulartype.

An optical frequency domain reflectometer(OFDR) based on a self-sweeping fiber laser
generating sequence of individual laser
modes is simulated. The effect of a small
frequency change for each mode whichleads to a parasitic signal in thereflectogram is taken into account. The
estimations for the achievable values of the
maximum fiber length and spatial resolution
in the proposed OFDR scheme – 10 metersand 14 μm, respectively – are calculated
based on the modeling.
