Optical phased array (OPA), a nonmechanical beam steering technology, greatly improves the efficiency and stability of optical systems. It offers various advantages, including lightweight construction, compact size, fast beamforming, and low power consumption, rendering it extensively applicable across various fields. This paper provides an overview of the research advancements in liquid crystal-based OPAs employed for beam steering in laser communication. Furthermore, we outline the current challenges and prospects of liquid crystal OPAs in laser communication.
