摘　　要：应用穆勒(Müller)矩阵对硅基平面光波导线路(Planar lightwave circuit PLC)补偿器中PDL对差分群时延(Differential group delay DGD)分布的影响进行了分析,在不同的PDL值下对各种不同级次的PLC单元级联情况的DGD值分布进行了讨论,并与Maxwell分布进行了比较,得到了在特定PDL值情况下最为优化的PLC级次.By utilizing Müller matrix approach, a detailed statistical analysis on the PDL （polarization dependent loss） dependence of differential group delay （DGD） in cascaded planar lightwave circuit （PLC） based PMD compensator is presented. For PDL values ranging from 0 to 10 dB, the DGD distributions were calculated with Monte Carlo simulation for cascaded PLC circuits of 3,4,5 and 15 segments. Based on comparison with Maxwell distribution, it was found that an optimized segment number for cascaded PLC circuit with PDL is around 4, and that DGD distribution exhibits a severe deviation away from the Maxwellian as PDL is above 8 dB.
