光波导开关的最新进展

THE LATEST PROGRESS OF OPTICAL WAVEGUIDE SWITCH

  • 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.

     

    Abstract: 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.
