摘　　要：无线光通信是一种新兴的通信技术,具有高速、大容量和安全性好等优势。然而,传统的无线光通信系统存在着单对单通信模式限制,无法满足多用户同时通信的需求。无线光通信中光学天线起着发射和接收耦合光信号的作用,一对多点发射天线可以拓展无线光通信的应用。对国内外一点对多点光学天线的发展进行总结,介绍了一对多光学天线的基本原理。对目前现有的几种一对多光学天线设计方案进行讨论。最后对该领域的发展趋势和未来发展方向进行展望。Optical antennas play the role of transmitting and receiving coupled optical signals in optical wireless communication,and a pair of multipoint transmitting antennas can expand optical wireless communication applications.Summarize the development of one-to-multipoint optical antennas at home and abroad,and introduces the basic principles of optical fiber array structure,three-concentric sphere structure and rotating paraboloid one-to-multipoint optical antenna.Finally,the development prospects of this field are foreseen.Optical wireless communication is an emerging communication technology with advantages of high speed,large capacity and good security.However,the traditional optical wireless communication system has the limitation of single-to-single communication mode,which can’t satisfy the demand of multi-user simultaneous communication.Optical antenna plays the role of transmitting and receiving coupled optical signals in optical wireless communication,and a pair of multipoint transmitting antennas can expand the applications of optical wireless communication.The development of one-to-multipoint optical antennas at home and abroad is summarized,and the basic principle of one-to-multipoint optical antennas is introduced.Several existing one-to-multipoint optical antennas design schemes are discussed.Finally,the development trend of this field and the future development direction are prospected.
