8-channel WDM soliton amplification and signal recovery

We demonstrate the signal recovery and amplification of eight soliton WDM channels using a single nonlinear amplifying loop mirror (NALM). The eight channels are amplified by 12 dB and nonlinear filtering provides 10 dB of noise suppression. We extend the functionality of the NALM to a multi-channel soliton WDM system. We demonstrate the NALM as a single module for amplification and noise suppression for eight simultaneous soliton WDM channels. This is the first time, to our knowledge, that a NALM has been used with more than two wavelength channels for WDM applications
