IS04–Flexible and Highly Scalable LiDAR for an FMCW LiDAR PIC based on Grating Couplers

In this paper three types of Silicon Photonics OPA architectures are proposed and investigated. Edge-fire optical phased array, that simplifies the design of the OPA. Second architecture is OPA with grating coupler antennas. Maximum steering angle for edge-fire OPA is ±44, FWHM is 0.10986. For GC OPA steering angle is ±20and FWHM=1.003116. Third architecture is the Slanted Grating Coupler with a FOV of 100◦.
