All-optical wavelength conversion scheme to reduce the crosstalk among the two multiplexed channels for polarization multiplexing system
We theoretically analyzed the polarization rotation effect in SOA for polarization-multiplexed signals. A polarization diversity parallel pump FWM scheme to reduce the crosstalk among the two multiplexed channels is proposed. Two system performances of conventional scheme and the proposed scheme are investigated by simulation. The simulation results indicate that the proposed scheme is better than the conventional scheme.
