PHASAR解复用器的原理及其性能综述与分析

Principles and Performance of PHASAR Demultiplexer

综述在密集波分复用系统里最富前景的 PHASAR(Phased Array)解复用器。首先分析了其多路干涉原理 ,接着研究器件的高色散特性 ,并介绍了 N× N波长互连的实现。然后重点讨论 PHASAR的性能问题 ,包括偏振无关性、插入损耗、串音、平顶频谱响应。最后简要介绍了 PHASAR的应用。

The most promising demultiplexer in DWDM system,Phased Array(PHASAR),is introduced.Followed with the analysis of principles,the high dispersion ability and realization of N×N wavelength interconnection are studied.Then the performance of PHASAR,including polarization independence,insertion loss,crosstalk and flat response,is discussed in detail.The application is briefly introduced in the last section.
