Abstract :
Repetition frequency tuning characteristics of a monolithic passively mode-locked distributed Bragg reflector semiconductor laser are investigated. By injecting current at a passive phase control section, a tuning range of 400 MHz is achieved while keeping the pulse characteristics nearly unchanged. Varying the absorber reverse bias offers an alternative to tune the frequency. By combining these techniques, a total tuning range of 1 GHz is realised
