摘要

We analyze the Q factor and the conversion efficiency of all-optical wavelength converter based on four-wave mixing in dispersion-shifted fibers at 10 Gb/s employing single sideband signal. We find that the Q factor of the converted signal is always higher for upper-single sideband signal with upward conversion in wavelength and for lower-single sideband signal with downward conversion. The four-wave mixing efficiency is higher when the pump wavelength is deviated positively relative to the fiber zero-dispersion wavelength. The used of low dispersion slope allows broad bandwidth and broad dynamic range of pump wavelength. From this study we depict the working characteristics of an all-optical wavelength converter for upper and lower single side band signals, providing guidelines to the utilization of these very promising technologies in the implementation of the future high bit rate all-optical networks.
