Phase regeneration of QPSK signal in SOA using single-stage, wavelength converting PSA
We demonstrate, for the first time, all-optical phase regeneration of a quaternary phase shift keying (QPSK) signal through phase sensitive amplification (PSA) in nonlinear semiconductor optical amplifiers (SOAs), using a scheme only previously demonstrated in highly nonlinear fibre (HNLF). We make...
