Abstract
The pulse conversion characteristics of an interferometric wavelength conve
rter using XPM in SOA and the influence of the ASE on the conversion proces
s are analyzed in the time domain. The variations of the output extinction
ratio without and with ASE are obtained for different SOA lengths and probe
-power split ratios. Fro the extinction ratio variation for the input signa
l power level, the optimized operating condition for a small ASE noise effe
ct is discussed. The influence of the ASE on the extinction ratio of the co
nverted signal as function of wavelength- conversion bandwidth is also obta
