摘要
首先对D W D M通信系统中的啁啾光栅色散补偿器进行了研究,介绍了啁啾光栅的耦合模算法,并针对其色散补偿的功能详述了用逆散射法设计啁啾光栅补偿器的过程;最后通过matlab仿真,给出了一个啁啾光栅滤波器8信道色散补偿反射率仿真图,从图可以看出,采用逆散射法设计的补偿器可以较好地达到D W D M系统中色散补偿的目的。
This paper discuss chirped FBG dispersion compensator for DWDM system. Then, we introduce the algorithm of chirped FBG couple mode, present the design process of chirped FBG dispersion compensator using inverse scatter according it＇s function of dispersion compensation. Finally, we give the reflected spectra graph of 8 channels by maflab simulation. From the graph, we can see the compensator designed by method of inverse scatter can compensate the dispersion in DWDM system perfectly.
