A Semiconductor Optical Amplifier Based Regenerator for Phase Modulated Signals
Amplification and simultaneous phase regeneration are necessary for phase modulated optical fiber communication system. In this paper,using semiconductor optical amplifier (SOA) as nonlinear medium,a nonlinear Mach-Zehnder interferometer (MZI)as the regenerator is designed. The formula of signal after the SOA based MZI regenerator is educed. For different incident power of signal,the relations between signal-pump phase difference and signal gain are discussed. The optimum parameters of input signal and pump are obtained. The distributions of phase and intensities for both the non-regenerated and regenerated signal are simulated. The results show thatthe SOA based optical regenerator has a good regeneration.
