Experiment study on reducing SOA induced crosstalk by CW light injection and dispersion management
Semiconductor optical amplifiers(SOAs) application are not as widespread as one would expect. The reason lies in the severe interchannel crosstalk experienced by the signals in a wavelength-division multiplexing(WDM) link using SOA. Theoretical study on channel crosstalk due to gain saturation in SOAs is presented. A significantly higher penalty is paid at more channels because of the gain saturation characteristic of SOAs. Crosstalk mitigation techniques in SOAs are studied. We have demonstrated theoretically and experimentally that a CW light propagating with signal can mitigate crosstalk in SOAs at channel rates of 40Gb/s. Reduction of crosstalk in SOA by amplifying dispersed WDM signals is confirmed experimentally. Based on the results of the experiment, a novel dispersion management scheme is proposed to prevent the interchannel crosstalk caused by cross-gain modulation.
