Claim Text:
1. An optical assembly apparatus comprising: a housing having an opening at one end and a wall having an optical feed-through; a receptacle subassembly configured to connect to an optical fiber, fit into the opening of the housing, and direct a light beam derived from a received optical signal within the optical fiber along an initial optical path through the opening in the housing; optical routing and wavelength demultiplexing elements mounted to an inner side of the wall of the housing and including a mirror and one or more additional optical elements off-path from the initial optical path of the light beam; and an electrical subassembly comprising one or more photodetectors and an integrated circuit, wherein the one or more photodetectors are optically aligned with the optical routing and wavelength demultiplexing elements; wherein the electrical subassembly defines a first functional layer of the apparatus, the optical feed-through defines a second functional layer of the apparatus, and the optical routing and wavelength demultiplexing elements define a third functional layer of the apparatus and the second functional layer being arranged between the first functional layer and the third functional layer.
