Phase-Preserving Power Limiting Function Using InP on SOI Photonic Crystal Nanocavity
Résumé
We report on the use of an InP/SOI hybrid photonic crystal nanocavity for the realization of a phase-preserving all-optical power limiter. This function is experimentally demonstrated with 20-Gbit/s NRZ-QPSK signals. Histogram-based measurements of the phase distributions indicate negligible variations of the phase noise while the amplitude fluctuations are suppressed, confirming the effectiveness of cavity switching for implementing the power-limiter function. Significant power penalty reduction is achieved, indicating a promising application for future photonic circuits.
