Clock extraction from 160-Gbit/s signal using optoelectronic phase-locked loop based on optical phase modulation and spectral filtering

摘要

We propose a novel phase-locked loop (PLL) for clock extraction using an optoelectronic phase comparator based on phase modulation and spectral filtering. With such PLL, a low-noise 10-GHz clock is extracted from a 160-Gbit/s signal.
