| Abstract: | 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. |
