Paper Abstract

Nonlinear Mach-Zehnder interferometers, when driven by a phase-locked local oscillator pump, provide phase-sensitive amplification to input signals. So phase-sensitive amplifier(PSA) can be used to realize phase regeneration of phase modulated signals. In the paper, we adopt kerr media-based nonlinear Mach-Zehnder interferometer to form a PSA to regenerate DPSK signals, and we propose a structure for the phase regenerating of DQPSK signals using two balanced PSAs. Theoretical analyses of all-optical phase regenerations of DPSK/DQPSK signals based on phase-sensitive amplification are presented. Simulations show that nearly ideal phase regeneration can be achieved for the DPSK/DQPSK signals.
