摘要
从均匀光纤光栅滤波器的窗口函数出发 ,研究了基于光纤光栅解复用器的光交叉连接中由于光栅非理想滤波特性引起的同频串扰问题 ,推导了两类同频串扰 (同源相干串扰和非同源串扰 )同时影响下的系统功率代价表达式 ,并由此计算了光栅耦合系数、光栅长度及偏振匹配因子等对系统性能的影响 .
Basing on the reflection spectrum of a FBG filter, the impacts of intraband coherent crosstalk and intraband incoherent crosstalk in an OXC based on demultiplexers using fiber Bragg grating (FBG) filters, deduces the system power penalty and discusses in detail the dependence of system degradation on the coupling coefficient, grating length and polarization matching factor, etc.
