Paper Abstract

We describe a method for precise pulse-repetition-frequency tuning of monolithic mode-locked laser diodes (MLLDs) by means of loss-induced change in the effective length of the distributed Bragg reflector. With this method, 39.8131-GHz (the SDH frequency) operation is achieved in a frequency tuning range of 1 GHz. The novel application of mode-locked laser diodes to all-optical clock extraction, one of the essential functions required in all-optical signal processing, is demonstrated at the 40-GHz SDH frequency.
