AWG作光路分插复用器串扰对信道数的影响

Impact of Crosstalk in Channel Numbers Based on Arrayed-waveguide on an Optical Add-drop Multiplexer

研究了阵列波导路由器作光路分插复用器（OADM）串扰的影响,其路由器含有m个上路/下路信道和n个传输信道。理论分析表明:随着上路/下路信道m和传输信道n的增加,串扰使OADM的信噪比QCT,成非线性下降、由于在阵列波导路由器中存在串扰,限制了基于 OADM的网络复用信道数。

The impact of crosstalk in an arrayed-waveguide (AWG) on an optical add-drop mul-tiplexer(OADM) is investigated. The OADM constitutes of m add/drop channels and n-pass channels. Theoretical analysis shows that the singal-to-noise ratio QCT of the OADM increases as either N or m is nonlinear degraded. Number of channels in a network based on OADM's is limited by crosstalk in the AWG router.
