We describe a mode-locked hybrid pulse source with a two-section laser
diode to obtain short mode-locked Pulses (23 ps) with an average powe
r of 7.8 mW, a high peak power of 137 mW, and a repetition rate of 2.5
1 GHz. The hybrid laser incorporates a two-section laser and an optica
l fiber cavity with an integrated Bragg reflector. The Bragg reflector
controls the operating wavelength to subnanometer precision and also
confines the bandwidth of the pulses so as to keep the time-bandwidth
product below 1.
