Phase-Preserving Amplitude Regeneration for RZ-DPSK Signals at 42.7 Gbit/s using Saturable Absorber
Résumé
We experimentally evaluate a novel all-optical phase-preserving amplitude regeneration technique for RZ-DPSK signals using saturable absorber. The device's capacity for amplitude noise reduction, hence preventing from nonlinear phase noise accumulation is demonstrated at 42.7 Gbit/s.
