Frequency tuning has been achieved in monolithic modelocked laser diodes through electrical control of the distributed Bragg reflector (DBR) effective length. A 0.5% frequency-tuning range has been obtained, which is wide enough to compensate for the frequency error that results from cavity length uncertainty when the usual cleaving process is used. Low-jitter 9.95328 GHz SDH frequency operation with a 6 ps transform-limited pulse output has been demonstrated.
