Performance improvement in XGM wavelength conversion exploiting SLAOLM

In this paper, a simple wavelength conversion scheme based on SLAOLM is proposed out for the first time, and its extinction ratio performance and noise characteristics can be improved simultaneously. Theoretical study shows that the conversion mechanism is still based on gain saturation effect, but the phase modulation effect existing in SLAOLM is helpful for extinction ratio improvement. Furthermore, the weak signal will be compressed and the strong signal will be amplified in the SLAOLM, then the Signal-Noise Ration (SNR) can be also improved. Experiment results shows that, after exploiting this scheme, the output extinction ration has been improved to be 10dB from 6dB, and the SNR has also been improved to be 13dB from 5dB.
