Plenary Talks
| Connie Chang-Hasnain Berxel Photonics, China Title: Very High Power and High Speed VCSELs for LIDAR and Datacom Applications |
| Abstract: Recent advances of VCSELs using distributed Bragg reflectors (DBR) and high contrastgrating (HCG) for multiple mode fiber optical communication and LIDAR applications will be reviewed Results include 106 Gbps PAM4-encoded directly modulated VCSEL and high power density (>4000 W/mm2) VCSEL arrays for LIDAR applications. |
| Yi Luo Tsinghua University, China |
Abstract: The optical devices are the backbone of fiber telecommunications, high speed 3D sensing such as Lidar systems, and VR/AR applications. In this talk, ultra-high speed DFB laser integrate with EA modulators,. ultra-wide band lithium niobate thin film optical modulators, and ultra-high speed photodetectors will be introduced. |
| Lars Samuelson SUSTech,China/Lund University, Sweden Title: Nanoscale Materials Science as basis for nanoLEDs for Displays and Communication |
| Abstract: While nitride LEDs with chip sizes of above several hundreds of microns have been widely applied for solid state lighting as well as in communications, there is an urgent need to reduce the chip size so that such LEDs can be used as individual pixels for next generation self-emissive displays. In this talk I will present our unique materials research that enables arrays of relaxed sub-μm sized InGaN platelets, virtually free from dislocations with a smooth top c-plane ideal for inGaNquantum well growth. The indium contents in such InGaN platelets can be tuned from 0 to 20%, so that the green and red-emitting lnGaN quantum wells are grown on such templates with a low level of strain similar to highly efficient blue-emitting lnGaN quantum wells on GaN films. Beside the obvious top application for advanced AR/VR/HUD applications, these ultra-small nanoLEDs may also find key applications in communication. |
| Ton Koonen Eindhoven University of Technology, The Netherlands Title: Recent Progress in High-Capacity Optical Wireless Communication |
| Abstract: Optical wireless communication can surpass the capabilities of radio-based wireless communication in many respects. When using accurately steered infrared beams, it can offer fiber equivalent high capacity at high user densities, while being highly secure, insensitive to EMl, an energy-efficient. This keynote talk presents recent advances in our indoor high-capacity beam steering technologies for all-optical bi-directional wireless communication including accurate automatic self-calibrated user localization. |
| Sarun Sumriddetchkajorn National Electronics and Computer Technology Center, Thailand Title: DIY Optical Spectrometers: From Lab to Market |
| Abstract: This talk overviews Do-lt-Yourself (DIY) approaches for the implementation of optical spectrometers. It covers the basic theory and engineering principle behind each approach. Ln addition, field and commercial prototypes are highlighted including ones campaigned through crowdfunding platform. |
| John Dudley Université de Franche-Comté, France Title: Machine Learning for New Insights into Ultrafast Nonlinear Fibre Optics |
| Abstract: The techniques of machine learning have tremendous potential to accelerate both basic science and important applications in ultrafast and nonlinear fibre optics. This paper will review as election of our work in this area. |
