Optical phased array technology can achieve high-speed and flexible directional radiation by adjusting and controlling the relative phase of optical antenna elements, gradually developing into the mainstream solution of non-mechanical beam control. It has the advantages of low power consumption, high integration, small size, and light weight, and can simultaneously control the transmission and reception of multiple beams, meeting the urgent development needs of future one-to-many laser communication. This article mainly elaborates on the current application status of three mainstream technical solutions of optical phased array technology in the field of laser communication, and compares the technical characteristics and application advantages and disadvantages based on liquid crystal, micro-electro-mechanical systems, and integrated optical waveguide platforms. Finally, some thoughts and suggestions are provided for the future development of optical phased array technology in the field of laser communication.
