Sub-Clock Extraction of Optical Signals at High Rates using an Opto-Electronic Phase-Locked Loop Based on Three-Wave Mixing in Periodically-Poled Lithium Niobate

Sub-clock extraction and clock synchronization of signals, at rates of 30 GHz and 10 Gbps, by an opto-electronic phase-locked loop based on three-wave mixing in periodically-poled lithium niobate, are demonstrated.
