Abstract
An optical communication system, suitable for simplex voice transmission is constructed, and demonstrated for straight line-of-sight, and for curved path operation using lenses and fiber optics. The system uses a pulsed gallium arsenide injection layer in the transmitter, operating at repetition frequency eight to fifteen kilohertz, and a p-I-n photodiode in the receiver. Pulse position modulation is used to transfer information as well as to trigger an avalanche transistor switch to drive the laser.
