Polarization-dependent chromatic dispersion and its impact on return-to-zero transmission formats

We describe the extension of importance sampling and multicanonical Monte Carlo methods to events with large polarization-dependent chromatic dispersion (PCD), and we compare the efficiency of the two simulation techniques. We then use these methods to simulate pulse transmission in a return-to-zero system with full first-order polarization-mode dispersion compensation at center frequency. Results show that PCD does not contribute significantly to the statistics of the residual pulse broadening.
