Abstract :
Summary for only given. Wavelength converters based on four-wave mixing (FWM) are potential candidates due to their format transparency, wide-band and ultra-fast operation. We investigate the effect of input pulse dispersion in a fibre four-wave mixer for high-speed (WDM) wavelength conversion using a 10 GHz, 6 ps pulse source. By introducing input pulse dispersion, we show improved distortion tolerance, and hence signal-to-noise ratio (SNR). Since the output of a FWM wavelength converter is also phase conjugated, introducing an equal amount of dispersion at the output will subsequently recompresses the pulse to its original width.
