Original Abstract Submitted
Disclosed are electronic devices that include an array of light emitting diodes and photosensors formed in a single semiconductor chip. The light emitting diodes may be structured as vertical exterior cavity surface-emitting laser diodes (VECSELs). The photosensors may be formed as resonant cavity photosensors (RCPDs). The VECSELs and the RCPDs of the array may be formed in a common set of semiconductor layers of the single semiconductor chip and separated by isolation regions formed in the common set of semiconductor layers. Also disclosed are dual chip transmitter-receiver systems including a first semiconductor chip having an array of both VECSELs and RCPDs formed in common set of semiconductor layers, and a second semiconductor chip electrically connected to the first semiconductor chip and including control circuitry to enable laser emission from the VECSELs and light reception by the RCPDs.
