VCSEL Photonics for Optical Interconnects and 3D Sensing

摘要

The 45 years' research and developments opened up a new world of VCSEL photonics, including sensors, optical interconnects in data center networks, LiDAR and high power sources. A lot of unique features have been proven. The market of VCSELs has been growing up rapidly and they are now key devices in data center networks. High speed VCSELs have been intensively developed for rapid growth in network traffics. The data rate reaches at 100 Gbps or higher. Also, 3D sensing has been attracting much attention 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 talk, the advances on VCSEL photonics will be reviewed, in particular, our recent activities on new functions and integration of VCSEL photonics. We address a lateral integration platform and new functions, including high speed coupled cavity VCSELs, their co-packaged optics, high power VCSEL amplifiers, high-resolution beam scanners and their integrations.
