Abstract
A smart pixel array is disclosed wherein a single optical beam can be used to transmit information to and from each subarea or cell of the pixel array. An optical P-I-N diode with an intrinsic MQW region is present in each subarea, and the optical beam is oriented to impinge on the diode. A first transmission gate couples information to be transmitted to the diode during a transmit interval, and information received by the diode is coupled through a second transmission gate to a receiver circuit during a receive interval. A third transmission gate couples a reset potential to the diode during spacing intervals between the transmit and receive intervals.
