摘　　要：通过对理论模型进行数值计算,给出H-PDLC体光栅的透射谱形状特性随参数的变化情况.其次,根据透射谱特性,提出一种新颖的EDFA动态增益均衡器的设计思想,并给出了计算机模拟动态增益均衡器的方法.模拟结果显示动态增益均衡器能够保持较好的工作状态.In this paper, characters of VPG's transmissive gain spectrum were studied using numerical solution. Using these characters, the idea of a novel dynamic gain equalizer (DGE) was presented and the way how to simulate the DGE was given as well. From the simulation, it can be seen that such DGE works well.
