  • Optical subassembly for passive alignment and method of aligning the same
    Patent number: 8714838
    Abstract: A subassembly for passive optical alignment includes a substrate, an alignment device on the substrate having a plurality of alignment holes, and an optical element aligned on the substrate with the alignment holes. A first lens device including a first lens on the alignment device aligns the first lens with the optical element to collimate light emitted from the optical element. A second lens device including a second lens collects the light from the first lens. A receptacle has a ferrule alignment hole penetrating the receptacle. A side of the receptacle is assembled on the second lens device to align the ferrule alignment hole with the second lens. The receptacle is assembled on the alignment device to align the second lens with the first lens. The ferrule alignment hole extends to a connector insertion hole formed on an opposite side of the receptacle that secures an external optical connector.
