Analysis of Raman assisted all-optical wavelength conversion by cross-phase modulation in high nonlinear fiber

All-optical wavelength conversion using cross-phase modulation in a high nonlinear fiber is demonstrated. The output extinction ratio and bit error rate dependence of the probe wavelength, probe power, input signal power, and fiber length are investigated. A 10-Gbit/s measurement has been performed and a 1.2-dB power penalty at 10 −9   bit error rate level is obtained.
