Abstract

All-optical synchronisation of self-pulsating diode lasers has recently attracted considerable attention for possible application to clock extraction, information processing, and pulse generation.¹ Two-section InGaAsP self-pulsating lasers have proved attractive for synchronisation, but single-section AlGaAs self-pulsing lasers developed for compact disk (CD) systems are low-cost and easily available.² Only electro-optic synchronisation of these lasers has been reported to date,³ and little is known about their all-optical synchronising properties. This paper reports synchronisation of selfpulsing CD lasers to a train of picosecond optical pulses.
