Kazuo Kuroda Yoshiaki Kato Shuji Sakabe Co-Chair Co-Chair Chair OPIC 2018 Organizing Committee OPIC 2018 Organizing Committee OPIC 2018 Steering Committee Professor, Utsunomiya University President, GPI Professor, Kyoto University President, The Laser Society of Japan

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 is held each year in Yokohama.

At the plenary session of OPIC 2018, four distinguished speakers will present on the following hot topics; ‘VCSELs in every car, every home and every mobile device’, ‘Diamond electronics and photonics: Application to quantum sensors’, ‘Photoacoustic tomography: Deep tissue imaging by ultrasonically beating optical diffusion’, and ‘Experiments on laser plasma accelerators with the BELLA laser and exploring the path towards future applications’.

OPIC 2018 is composed of 14 professional conferences. We are very pleased to welcome IoT-SNAP (IoT Enabling Sensing/Network/AI and Photonics) 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 of Agriculture, Forest and Fishery (MAFF), the Ministry of Health, Labor and Welfare (WHLW), the Ministry of Land, 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 we would like to thank the founding organizations and companies for their strong support of OPIC 2018.

First Session fast modulation, thereby lending itself well to high- speed data transmission or short pulse operation. However, the one outstanding additional property

Plenary that sets VCSELs apart from any other laser is Plenary Speech its compatibility to electronics manufacturing flows. 9:15 - 9:55 VCSELs are processed and tested on wafer scale, and conveniently integrate into printed circuit boards just VCSELs in every car, every home and like almost any other electronics component. This has every mobile device enabled a supply chain for high volume devices such as time-of-flight sensors or optical transceivers with unmatched price points.

Main present day applications: Optical interconnects Optical interconnects with distance range of up to a few 100m today mostly employ VCSELs to transmit data. Transmission rates gradually moved from 1Gbps Dr. Joseph Pankert to 25Gbps over the last decade, and soon will reach 50- Philips Photonics 100Gbps through pulse amplitude modulation schemes [email protected] (PAM4). Parallel operation of a manifold of transmission channels has enabled transceivers with more than Abstract 1Tbps bandwidths. Today, VCSEL based transceivers Vertical Cavity Surface Emitting Lasers (“VCSELs”) are widely used in large data centers, but the technology have been first demonstrated more than 40 years ago by is at the brink of also penetrating consumer applications. Kenichi Iga. First commercial applications in optical data transmission were introduced more than 20 years Optical sensors ago, but it appears that true mass adoption of VCSELs Optical depth sensors based on the time-of-flight is happening only now. The main drivers for this (ToF) principle are one of the fastest growing VCSEL development are widespread use of VCSEL in optical applications. Fig. 1 shows one embodiment of so-called sensors in mobile devices (proximity, auto-focus, direct ToF wherein a VCSEL creates a short light pulse identification) and the ever-increasing data traffic that (or a sequence of pulses) and triggers a single photon requires optical interconnects even for consumer avalanche diode (SPAD) detector.

Moreover, industrial thermal processing may largely benefit from increased VCSEL proliferation in other areas. The first part of the talk will cover the basic properties of VCSELs and its main applications. The second part will address current developments and new fields that VCSEL technology may conquer in the future. Fig.1: Time of flight detector principle The main reason for using VCSELs as the light Introduction source of choice is the narrow spectral range, which A VCSEL is a (micro-) laser; it is monochromatic, allows equally narrow filtering of ambient light from coherent, and has a beam shape that conveniently reaching the detector. Moreover, VCSEL, unlike LEDs, couples into optical fibers. The small cavity allows for provide focused light beams, can be modulated at high

Smartphones, laptops, drones, robots and cars increasingly embed functions to map the 3D space around them for reasons of AR/VR, identification or navigation. The applications range all the way to LIDAR systems in autonomous cars resolving small obstacles more than a hundred meters ahead.

VCSEL arrays have recently also been widely used Already today, designs make use of the wafer scale for cw illumination. In combination with optical elements technology, e.g. in datacom chips, where several VCSEL like diffusors and dot pattern generator, this is used for channels are placed next to each other on the same identification in smart phones and soon also in cars. chip. Further functional integration is likely to come in the near future. Fig.5 shows an example, where micro lenses are integrated on wafer scale onto the VCSEL chips. Other optical functions for polarization and mode control have been demonstrated already.

VCSEL into more and more new applications and make it the most popular diode laser 40 years after its Industrial thermal processing invention. VCSELs will be everywhere. Although individual VCSEL emitters have a few 10mWs of power only, arrays combine many of these emitters to provide power densities of several Watts/ mm2 emitted from the chip surface. Tiling many of these chips in large-scale systems opens up new ways to do industrial thermal processing. In Fig.3 a picture shows a VCSEL system of a width of 20 cm that provides 10kW Fig.5: Integrated polymer lenses on top of a VCSEL array of optical power. Power densities are orders of magnitude higher than what can be achieved with e.g. halogen Dr. Joseph Pankert studied Physics at the universities lamps.

High-resolution pure optical imaging—such as confocal microscopy, two-photon microscopy, and optical coherence tomography—is limited to superficial imaging within the optical diffusion limit (~1 mm in the skin) in scattering tissue. By synergistically combining light and sound, PAT in the form of either photoacoustic computed tomography or photoacoustic microscopy provides deep penetration at high ultrasonic resolution and high optical contrast. PAT is the only modality capable of imaging across the length scales of organelles, cells, tissues, and organs (or small-animal organisms) with consistent contrast.

Although many challenges remain, this new laser plasma accelerator the injectors are typically technology is at the brink of offering a profoundly relying on self-trapping, downramp or shock injection, different way in which we may build particle accelerators ionization injection or laser triggered injection. The such as those used in light sources, compact gamma ray structures that guide intense laser pulses are pre- sources, medical cancer therapy devices, and even formed plasma channels and the power sources are colliders. intense laser pulses to excite large amplitude electric fields in these waveguides, via efficient coupling of high Content power laser pulses. Experiments have been conducted In 1979, a new method for particle acceleration was to understand how to guide ultra-intense laser pulses proposed that relies on the excitation of large amplitude (>1019 W/cm2) over extended distances in preformed plasma waves with intense laser beams. In the past ten plasma channels and how to generate high energy to fifteen years, lasers became available that produce electron beams from such structures. An example of a 9 intense short laser pulses with duration of tens of cm long plasma waveguide that is formed through a femtoseconds and peak power in the tens to now even a capillary discharge in hydrogen gas is shown in Figure thousand terawatt at higher and higher repetition rates. 2.

We applied second-harmonic-generation (SHG) microscopy to monitor the collagen fibers produced by osteoblast-like cells. To evaluate the influence of mechanical stimulation on collagen synthesis and maturation, we compared SHG images of osteoblast-produced collagen fibers with and without a cyclic stretch stimulus. We acquired SHG images every 7 days for 3 Oral Program weeks at different stimulus conditions. Image analysis of the average SHG intensity indicated that the amount of osteoblastic collagen synthesis was significantly enhanced by the cyclic stretch compared with the the non-stretched condition, while there was no significant difference between the two stimulus conditions. Furthermore, the maturity of the collagen fibers was not affected in the early stage of bone formation by the mechanical stimulus.
