Simultaneous All-Optical Regeneration of Multi-Wavelength Signals

Regeneration of multi-wavelength-channel signals, using saturation of four-wave mixing in fiber, was studied. Because the signal phase is almost preserved in this scheme, it is suitable for amplitude noise reduction of phase-modulated signals. In this study, (1) simultaneous noise reduction of 10Gbps x 3ch differential phase shift keying signals and consequent reduction of nonlinear phase noise, (2) regeneration of 10Gbps x 2ch OOK signals using higher-order four-wave mixing, and (3) a scheme of adaptive delay control for achieving suitable time multiplexing of channels, were demonstrated.
