SOLID STATE LIDAR OPTICAL DEVICE AND LIDAR OPTICAL DEVICE

One or more embodiments of the present disclosure relate to a solid state light detection and ranging, LIDAR, optical device and LIDAR, where the solid state light detection and ranging, LIDAR, optical device includes: a carrier. A photonic integrated circuit (PIC) secured to a carrier. The PIC includes an input coupler and an array of output couplers, and a switchable optical network connects the input coupler to a selected different output coupler in the array of output couplers. A laser source is adjacent to the input coupler, mounted to the PIC such that laser light generated by the laser source is injected into the input coupler. An optical stack is adjacent the output coupler array, mounted to the PIC to receive laser light extracted by the output coupler array from the switchable optical network. The optical stack includes a microlens array positioned such that a bottom surface thereof is mounted to the PIC, and a microprism array stacked on the microlens array. 本公开的一个或多个实施例涉及固态光检测和测距LIDAR光学装置及LIDAR光学装
