Abstract: An apparatus includes a focal plane array configured to receive incoming light. The apparatus also includes a readout integrated circuit configured to generate electrical signals based on the incoming light received by the focal plane array. The apparatus further includes a photonic integrated circuit positioned between the focal plane array and the readout integrated circuit. The photonic integrated circuit is configured to receive the electrical signals and generate output optical signals based on the electrical signals. In some cases, the apparatus may include electrically-conductive vias electrically coupling the focal plane array and the readout integrated circuit, where at least some of the electrically-conductive vias may extend through the photonic integrated circuit. The focal plane array, the readout integrated circuit, and the photonic integrated circuit may form at least part of a monolithic structure.
