摘要
光学相控阵技术通过调节和控制光学天线阵元的相对相位,可实现高速灵活的定向辐射,逐渐发展成为非机械式光束控制的主流方案.其兼具功耗低、集成度高、体积小、质量轻等优点,可以同时控制多波束的收发,满足未来一对多激光通信的迫切发展需求.本文主要针对光学相控阵技术当前三种主流的技术方案在激光通信领域的应用现状进行阐述,对比给出了基于液晶、微机电系统和集成光波导平台的技术特点和应用优劣.最后针对光学相控阵技术在激光通信领域的未来发展,给出了笔者的一些思考与建议.
Abstract
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.
