Paper Abstract

This work describes recent results investigating the operation of a novel device arrangement which is capable of being integrated using present optoelectronic materials. The system utilizes an external cavity laser diode and an avalanche photodiode (APD) in a feedback arrangement and is capable of providing a stable train of picosecond pulses without the use of saturable absorbers or external signal generators. The role of amplification in the electronic feedback circuit is examined in detail.
