本文提出了一种用于四相相移键控(QPSK)信号相位再生的环路相敏放大器(PSA)。与信号输出相位被锁定到两个值之一(例如,0或π),由于具有两个泵浦光的环路配置,所提出的方案输出具有相差π/2的四个相位值之一的信号光。使用该PSA方案可以实现全光QPSK信号再生。
In this paper, phase-sensitive amplification (PSA) in a loop configuration for phase regeneration of quadrature phase-shift keying (QPSK) signals is proposed. Unlike the conventional PSA schemes in which the signal output phase is locked to one of two values (e.g., 0 or π), the proposed scheme outputs signal light with one of four phase values different by π/2, owing to the loop configuration with two pump lights. All-optical QPSK signal regeneration can be achieved by using this PSA scheme.
