ABSTRACT:
An input optical data pulse 120 encoded by pulse amplitude modulation is branched into two parts by an optical coupler 111, and one part is input to an optical clock generation device, such as mode-locked laser diode (MLLD) 113 and the other part is input to an optical/optical intensity modulator, such as semiconductor optical amplifier 110 or electro-absorption light intensity modulator 210. A regenerated optical clock pulse drives the optical/optical intensity modulator and input optical data pulses 120 are intensity-modulated to serve as optical data pulses 121 which are output. An input optical data pulse can drive the light intensity modulator.
