We propose a prescaled phase-locked loop (PLL) using a simple optoelectronic phase comparator based on phase modulation and spectral filtering. Our phase comparator has a high dynamic range of over 9 dB and a high sensitivity comparable to that using an electrical mixer. A PLL composed of our phase comparator enables to extract a low-noise 10-GHz clock from a 160-Gbit/s optical-time-division multiplexed (OTDM) signal.
