Abstract

We study the effects of dual feedback on a passively mode-locked semiconductor laser using a delay differential equation model. Timing jitter reduction is achieved provided that one of the feedback cavities is resonant with the laser cavity. Maximal jitter reduction occurs when both feedback cavities are resonant. As with single cavity feedback there is a locking range in the feedback delay length about the main resonances. When both feedback delay lengths are tuned appropriately within this locking range simultaneous timing jitter reduction and repetition rate tuning can be achieved, making it interesting for device applications.
