摘　　要：为了解决长途高速通信系统中偏振模色散对系统性能的影响,提出了一种高度集成化的偏振模色散(PMD)光学补偿解决方案.基于无转动部件的偏振控制器(PC)原理,利用硅平面光波导线路(PLC)技术,实现了一个无限偏振控制系统,从而完成对偏振模色散的补偿.对该模型利用PMD向量的级联规则理论,通过蒙特卡洛统计方法分析得出,三段级联的PLC系统与麦克斯韦理论分布基本吻合,并接近十二段传统非线性晶体型PMD补偿器的补偿特性.级联式的PLC系统是传统PMD补偿器的一种较好的集成化升级方案.A novel cascaded planar lightwave circuit （PLC） based polarization-mode dispersion （PMD） compensator was proposed to compensate the PMD for long haul high speed communications, and a detailed statistical analysis of PMD generated by cascaded PLC circuits was presented. This kind of PLC on silicon substrate offered a promising on-chip integrated solution. Using the concatenation rule of PMD vectors derived by Gisin and Pellaux, the distributions of the first-order PMD produced by various multiplestage PLC circuits were obtained by Monte Carlo simulation with respect to the phase shift introduced by heating elements in the circuits. The generated PMD was compared with a standard Maxwell distribution and that of a 12-stage nonlinear crystal based PMD compensator. The performance of the 3-stage cascaded PLC circuit was close to that of a crystal-based PMD compensator, while having significant reduction in packaged size and enhancement in stability.
