Wavelength conversion of a polarization multiplexed RZ-ASK-DPSK signal using four-wave mixing (FWM) in a 32-cm Bi-NLF incorporated in a polarization diversity loop is demonstrated. The 40-Gb/s RZ-ASK-DPSK input signal is combined with a 30-dBm CW pump using a 3-dB coupler. After the FWM wavelength conversion, the output signal at 1546.8 nm is filtered out using an optical bandpass filter. Eye measurements...
We demonstrate polarization-insensitive wavelength conversion of 10-Gb/s DPSK signal using a polarization-diversity scheme for four-wave mixing in 32-cm bismuth-oxide highly nonlinear fiber. The polarization dependence is <1 dB and the power penally is 3 dB.
Wide-band wavelength conversion is obtained in a 32-cm highly nonlinear bismuth oxide fiber using dual-pump four-wave mixing. The conversion for a 10-Gb/s NRZ-DPSK signal shows a power penalty below 4 dB over a 30-nm range.
