Abstract :
A tandem configuration for wavelength conversion using four-wave mixing in a semiconductor optical amplifier is suggested as a method to obtain enhanced signal-noise ratios due to longer interaction length. Experimental results show a decrease in the overall penalty for wavelength conversion at 10 Gbit/s. Furthermore, good system performance can be obtained at much lower input signal powers than for a single device
