论文摘要
The 40 years' research and developments of vertical cavity surface emitting lasers (VCSELs) opened up a new world of VCSEL photonics, including, sensors, optical interconnects in data center networks, laser printers, LiDAR and high power sources. The market of VCSELs has been growing up rapidly and they are now key devices in data center networks based on multi-mode optical fibers. High speed VCSELs beyond 50 Gbps are expected for future data center networks. 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. A big market is prospected for 3D depth camera, which was installed in iPhone X. A non-mechanical optical beam scanner is a key element for use in various applications such as laser displays, laser sensors and free-space optical communications. A mechanical beam scanner has been widely used, but non-mechanical scanner is attracting much attention for compact solid state LiDAR applications in recent days. We proposed and demonstrated a beam steering device based on a VCSEL structure, showing the record high-resolution beam steering. In this talk, the advances on VCSEL photonics will be reviewed. We address a lateral integration platform and new functions of VCSELs, including high speed coupled cavity VCSELs with low power consumption, high power VCSEL amplifiers of over 5W in a single-mode operation, high-resolution beam scanners, dot projectors and their integrations.
