Abstract: In this paper, the working principles of silicon-based phased array LiDAR and silicon-based optical switch array LiDAR are discussed, and the development of these two silicon-based all-solid-state LiDAR is reviewed. Among them, the research on silicon-based phased array LiDAR started earlier and has achieved remarkable results, but the control circuit of large-array silicon-based phased array LiDAR is complex and difficult to implement. Because of its simple working mode and low technical threshold, the silicon-based optical switch array LiDAR has developed rapidly, so the performance gap with the silicon-based phased array LiDAR is smaller and smaller.
Keywords: iDAR; silicon-based; optical phased array; optical switch array
