Abstract :
We have theoretically and experimentally investigated polarization insensitive all-optical wavelength conversion for polarization multiplexing signal based on orthogonal pump four-wave mixing in nonlinear optical fiber. After wavelength conversion based on 1 km high-nonlinear optical fiber with polarization insensitivity, the power penalties of 2.5 Gbit/s optical OOK intensity and 10 Gbit/s differential phase-shift keying orthogonal signals are less than 0.5 and 0.8 dB, respectively.
