Patent ID: 8340528

Claim:
An optoelectronic device, the optoelectronic device comprising: a substrate including a group IV semiconductor layer positioned along a light beam axis; an optical transceiver, including an optical detector and optical transmitter, the optical detector being positioned along the light beam axis and configured to receive an incoming light beam and to detect a first wavelength and/or range of wavelengths and the optical transmitter being positioned along the light beam axis and configured to transmit an outgoing light beam, wherein the outgoing light beam includes a second wavelength and/or range of wavelengths, the optical detector comprising one or more materials that are optically unresponsive with respect to at least a portion of the outgoing light beam so that an optical signal path for the outgoing light beam is defined that extends from the optical transmitter through the optical detector and the optical detector and the optical transmitter being stacked one on top of the other; and a control circuit positioned adjacent the optical transceiver and in electrical communication with the optical transceiver, wherein the substrate, the optical transceiver, and the control circuit are monolithically formed in a stacked configuration, the substrate positioned in a first layer of the stacked configuration without the optical transceiver or the control circuit, the optical transceiver positioned in a second layer of the stacked configuration without the substrate or the control circuit, and the control circuit positioned in a third layer of the stacked configuration without the substrate or the optical transceiver.
