Abstract
The impact of the first-order and second-order PMD on the performances of optical switching with NOLM is studied by the split-step Fourier method (SSFM) based on the coupled nonlinear Schrodinger equation (CNLSE), including optical eye graphs, power transmission function of the NRZ code and the Q-factor penalty of different code patterns at different working speeds. The simulation results show that the switching performances are deteriorated badly by PMD, and using the right code pattern can reduce the impact of PMD partially. Furthermore, the compensation method of PMD by the polarization-maintaining fiber (PMF) inside the fiber loop of NOLM is put forward. It influences the original switching performances to the least extent when the PMF is located in the middle of the fiber loop.
