摘要
随着光纤通信技术的不断发展，作为光分插复用（OADM）和光交叉互联（OXC）核心器件的光开关作用日益突出.文章从开关单元结构、材料及调制机理三个角度对波导开关进行了划分，阐述了波导开关的基本原理以及当前的研究进展，对面临的一些技术挑战进行了分析，并提出了自己的观点.
With the development of opticalfiber communications, the function of optical switches is becoming increasingly prominent since they serve as kernel devices for optical add\|drop multiplexing(OADM)and optical cross connecting(OXC). This article classifies optical waveguide switches from three different angles: unit structure, material and modulating mechanism. We also discuss the basic principles and latest developments of waveguide switches, and analyze the technological challenges with comments from our point of view.
