Self-phase modulation in a highly nonlinear fiber (HNLF) had been demonstrated to have regeneration capabilities when associated with shifted filtering. In this paper, we show how a saturated semiconductor optical amplifier (SOA) can enhance this concept by optimally transferring the signal power to the shifted-filter's side of the spectrum. We also provide a detailed optimization analysis of the filter's detuning and bandwidth by means of numerical simulations. In this study, we consider an amplitude and phase noise degraded return to zero differential binary phase shift keyed signal (RZ-DBPSK).
