Title: VCSEL Photonics for High-speed Optical Interconnects and 3D Sensing
Abstract: 
A vertical cavity surface emitting laser (VCSEL) was invented in 1977. The over 40 years’ research and developments opened up various applications including datacom, sensors, optical interconnects, spectroscopy, optical storages, printers, laser displays, laser radar, atomic clock and high-power sources. A lot of unique features have been already proven, including high-speed operations, low power consumption, small footprint, wafer-scale testing, low-cost packaging, ease of fabrication into arrays. A VCSEL is the most popular choice for use in optical interconnection of datacenters and supercomputers. High speed VCSELs are attracting much attention for rapid growth in network traffics. Also, 3D sensing has been accelerating the VCSEL market for a wide range of applications such as face ID in mobile phones, LiDAR for automatic driving cars, distance sensor of robot, security camera, and motion sensors in virtual reality. In this presentation, the current state and future prospects of VCSELs will be addressed, focusing on high-speed, high-power VCSEL photonics and new functions.
