Title:
OPTICAL RECEIVER
Document Type and Number:
WIPO Patent Application WO/2023/022110
Kind Code:
A1
Abstract:
An optical receiver comprising: a light receiving element; a carrier substrate; a dielectric layer; a base; a first electrically conductive film; a second electrically conductive film; an electrical conductor; and a transimpedance. The first electrically conductive film is provided between the light receiving element and the carrier substrate. The second electrically conductive film is provided between the carrier substrate and the dielectric layer, and has a parasitic capacitance between the second electrically conductive film and a first wiring pattern of the first electrically conductive film. The electrical conductor is electrically connected to the first wiring pattern and to the second electrically conductive film. The transimpedance has a first pad electrically connected to the first wiring pattern via a wire. The capacitance between the second electrically conductive film and a major surface of the base is greater than the parasitic capacitance. The inductance of the electrical conductor is smaller than the inductance of the wire.
