All-optical regeneration of DQPSK/QPSK signals based on phase-sensitive amplification
چکیده انگلیسی

An all-optical regeneration scheme for DQPSK and QPSK signals using phase-sensitive amplifiers (PSAs) is studied and its effectiveness is investigated through numerical simulations. By leveraging the ability of PSAs to provide phase and amplitude regenerative amplification, we show significant simultaneous suppression of both phase and amplitude noises of (D)QPSK signals under optimized conditions. The reduction in the phase noise variance of a noise-corrupted DQPSK signal obtained by one such regenerative amplification can be as large as ∼5.5 folds, showing its good potential for distributed optical regeneration of (D)QPSK signals.
