ABSTRACT:
An optical clock regenerator using a laser includes an optical modulator for mode locking in a laser resonator. The optical modulator is driven by an intensity-modulated optical signal. When an intensity-modulated optical data pulse train including a clock frequency component close to a frequency n (n is an integer) times or one-nth times a resonance frequency of the laser resonator is input to the optical modulator, the laser outputs clock pulse light locked by the frequency n times or one-nth times a clock frequency of the optical data pulse train. The optical data pulse train and the laser resonator are spatially separated from each other.
