A Polarization Multiplexing Technique to Mitigate WDM Cross-Talk in SOAs

Cross-talk arising from gain saturation effects in semiconductor optical amplifiers (SOAs) causes major system impairments in WDM transmission of multiple optical channels. We propose a novel polarization multiplexing technique to mitigate the gain saturation effects in SOAs and demonstrate error-free WDM transmission over a 45 km metro-like fiber link for a 2 channel case using a SOA.
