Cross-phase modulation (XPM) changes the state-of-polarization (SOP) of the channels through nonlinear polarization rotation and induces nonlinear time dependent phase shift for polarization components that leads to amplitude modulation of the propagating waves in a wavelength division multiplexing (WDM) system. Due to the presence of birefringence, the angle between the SOP changes randomly and as a result polarization mode dispersion (PMD) causes XPM modulation amplitude fluctuation random in the perturbed channel. In this paper we analytically determine the probability density function of the random angle between the SOP of pump and probe, and evaluate the impact of polarization mode dispersion on XPM in terms of bit error rate, channel spacing etc for a two channel intensity modulation-direct detection WDM system at 10 Gb/s. It is found that the XPM induced crosstalk is polarization independent for channel spacing greater than 3 nm or PMD coefficient larger than 2 ps/√km. We also investigate the dependence of SOP variance on PMD coefficient and channel spacing.

AbstractAdvanced modulation schemes, particularly the phase-modulated signals, have already drawn huge research interests for ultra-high speed long-haul lightwave transmission systems. We have considered 40 Gbit/s optical RZ pulse propagating in a periodically dispersion managed (DM) single channel system with negative residual dispersion. We investigate the effects of negative residual dispersion on intra-channel cross-phase modulation (IXPM)-induced phase shift. Analytical estimation for phase shift has been deduced using perturbed variational formulation. We therefore explore the impact of variation of various parameters such as transmission distance, duty cycle, bit rate, etc. on phase shift. The outcome of our work is to explore the performance of the dispersion compensated system with some negative residual dispersion so that the IXPM-induced phase shift remains low in optical fiber communication.
