High-frequency and low-jitter optical pulse generation using semiconductor mode-locked lasers

This paper describes optical short pulse generation at over 100 GHz using semiconductor mode-locked lasers integrated with electroabsorption modulators. Active mode locking at 102 GHz is performed by a half-frequency modulation technique. The phase noise of a generated pulse train is evaluated by means of an opto-electrical down conversion technique using a unitraveling-carrier photodiode. A low-timing jitter of 0.23 ps is obtained for 102-GHz 2.4-ps pulses.
