Abstract: An optoelectronic device includes a first semiconductor die, having first and second surfaces and including a first array of transceiver elements. Each transceiver element includes an optical transducer, which directs outgoing coherent optical radiation through the first surface toward a target and to receive incoming optical radiation that has been reflected from the target. A single-photon optical detector outputs electrical pulses in response to photons of the incoming optical radiation. A waveguide conveys the incoming optical radiation from the optical transducer to the single-photon optical detector. A second semiconductor die is bonded to the second surface of the first semiconductor die and includes a second array of logic circuits, which are coupled to receive and process the electrical pulses output by the single-photon optical detectors in corresponding ones of the transceiver elements.
