Abstract: The dynamic characteristics of a wavelength converter based on cross-gain modulation in semiconductor optical amplifiers is analyzed theoretically.For first time, the dynamic carrier recovery time is used to equivalent the high frequency saturation filtering effect of the signal channel during the calculation and it is proved by comparing the outputting waveform gottenthrough this way and the experiment results reported in other papers.Ways to reduce the influence of the chirping on the converted signal and ISI of the converted signal are discussed.

Key words: optical communication, all-optical wavelength conversion, dynamic carrier recovery time, chirping
