摘要
针对电交换路由成为全光网通信和密集波分复用等高速信息传递网的电子瓶颈的现状,开展对全光光分插复用器的理论和实验研究。介绍了基于Mach-Zehnder干涉仪和FBG结构、基于FBG和光环行器结构以及一体化光纤光栅耦合器结构的光分插复用器的工作原理,实际构建了3种结构的光分插复用器,并分别搭建测试系统进行了单波长光信号上/下行实验研究,对比了这3种光分插复用器结构的性能和优缺点,为全光光分插复用器的设计制作提供了参考。
Optical add/drop multiplexer（OADM） is a key device for fiber sensing dense wavelength division multiplexer and future all-optical-net communication to replace electronic router,which is the bottleneck of high-speed information transmission.The work principles of the OADM based on the structure of Mach-Zehnder interferometer and fiber Bragg grating（FBG）,the structure of optical circulator,FBG and the structure of integrative fiber grating coupler（FGC） were introduced.Three configurations of OADM were built and were experimentally investigated to test their performance.The advantages and disadvantages were concluded and the basis for the design and fabrication of OADM was provided.
