Electronic Devices with Transmitter-Receiver Array
This abstract first appeared for US patent application 20250102631 titled 'Electronic Devices with Transmitter-Receiver Array
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.
