Title: Optical receiver method and apparatus

Abstract: A method for making an optical receiver assembly that can receive optical signals via an input optical fiber and can generate output electrical signals, including the following steps: providing an open-ended cavity formed of insulating material, such as a ceramic, comprising a base, peripheral sidewalls, and an open end opposite the base, the outside surface of the base defining a first surface and the inside surface of the base defining a second surface; disposing a first conductive region on a portion of the first surface and a second conductive region on a portion of the second surface; mounting, on the first surface, a semiconductor photodetector device having an active region for communicating optically with the input optical fiber, and coupling an electrical output of the photodetector device with the first conductive region; mounting, on the second surface, an amplifier that is electrically coupled with the second conductive region and produces the output electrical signals; and providing at least one conductive via through the thickness of the base and between the first and second conductive regions for coupling the electrical output of the photodetector device with the amplifier.
