Abstract :
An ultrahigh-frequency optical pulse train from a monolithic mode-locked laser diode was stabilized by a novel method. When a stabilized optical pulse train was injected into a passively mode-locked laser diode whose repetition frequency was an integer multiple of the injected one, the output optical pulse train was harmonically synchronized and highly stabilized. This kind of operation was observed up to 40 GHz with 1 GHz optical pulse injection.
