Active modelocking of semiconductor diode lasers in an external cavity by synchronous electrical pumping is a simple and attractive method for generation of short optical pulses in the wavelength region of interest for optical communication [1]. Up to now, most attention has been paid to the time-averaged behaviour of pulse width, optical spectrum and time-bandwidth product, but pulse intensity fluctuations are of major importance in communications and logic applications. In this paper we investigate this type of noise and demonstrate a partial suppression by cw injection locking. Similar results have previously been demonstrated in a CO2 laser [2].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
