Abstract
Disclosed is an optical communication system which uses the self-pulsating frequency of a self-pulsating laser diode as a microwave subcarrier to transmit digital information. The system has a transmitter comprising a self-pulsating laser diode and a modulating mechanism for encoding the laser's self-pulsating microwave sub-carrier. In one embodiment, the modulating mechanism employs frequency-shift keying for digitally encoding the sub-carrier. Furthermore, the optical communication system has a receiver including a photodetector and a signal decoder.
