Abstract

Active modelocking of semiconductor lasers in an external cavity is a simple and useful technique for generation of short optical pulses in the wavelength region of interest for optical communications. Up to now, most attention has been paid to the time-averaged behaviour of pulse width, optical spectrum and time-bandwidth product, although noise, both at baseband and optical frequencies, is of major importance in communication and logic applications. In this paper, we investigate the noise behaviour of a modelocked GaAlAs laser and demonstrate a partial suppression by cw injection locking. A similar technique has previously been demonstrated with CO2 lasers [1].
