Silicon photonics-based beam scanning technology is expected to be introduced into short-distance free-space optical (FSO) communication applications such as inter/intra rack communications in data centers and indoor mobile communications in beyond-5G mobile communications.In this report, we present our recent work about a broadband two-dimensional (2D) Si beam scanning device that integrates 128-port three-dimensionally-structured optical surface couplers.
