Abstract

An optoelectronic device for generating an optical pulse train comprises a phase modulator (9) for modulating the phase of an optical signal received from a laser (3) in accordance with a clock signal and outputting a phase modulated signal. The device further comprises an all-pass optical filter (10) for receiving the phase modulated signal and modifying the phase modulated signal to produce intensity modulation. Such a device provides higher output peak power compared to a conventional pulse carver.
