摘要： A process of making a coupling device for physically and optically coupling an optical fiber to route optical signals to/from optical receiver/transmitter. The coupling device includes a structured reflective surface that functions as an optical element that directs light to/from the input/output ends of the optical fiber by reflection, and an optical fiber retention groove structure that positively receives the optical fiber in a manner with the end of the optical fiber at a defined distance to and aligned with the structured reflective surface. The open structure of the structured reflective surface and fiber retention structure lends itself to mass production processes such as precision stamping. The coupling device can be attached to an optical transmitter and/or receiver, with the structured reflective surface aligned to the light source in the transmitter or to the detector in the receiver, and adapted in an active optical cable.

摘要： A hermetic optical subassembly includes an optical bench having a mirror directing optical signals to/from an optical waveguide, a carrier supporting a photonic device, and an intermediate optical bench having a mirror directing optical signals between the photonic device and the optical bench. The optical bench and the intermediate optical bench optically aligns the photonic device to the waveguide along a desired optical path. In one embodiment, the photonic device is an edge emitting laser (EML). The mirror of the optical bench may be passively aligned with the mirror of the intermediate optical bench. The assembled components are hermetically sealed. The body of the optical benches are preferably formed by stamping a malleable metal material to form precise geometries and surface features. In a further aspect, the hermetic optical subassembly integrates a multiplexer/demultiplexer, for directing optical signals between a single optical fiber and a plurality of photonic devices.

摘要： A Mux/Demux subassembly includes a stamped optical bench, which includes an array of stamped reflective surfaces for redirecting optical signals. Alignment features and components of the Mux/Demux subassembly are integrally formed on a stamped optical bench, defining a desired optical path with optical alignment at tight tolerances. The optical bench is formed by stamping a malleable stock material (e.g., a metal stock), to form precise geometries and features of the optical bench.

摘要： An expanded beam ferrule includes a first ferrule halve having reflective surfaces and a second ferrule halve, which together retain optical fibers. The reflective surfaces output light perpendicular to the mid-plane of the ferrule. A sleeve aligns the external surface of two similar ferrules, with the reflective surfaces of the respective ferrules facing each other. Output light from an optical fiber held in the first ferrule is bent and collimated by a reflective surface, transmitted to the facing reflective surface in a second ferrule aligned by the sleeve, which bends the light to input to the optical fiber held in the second ferrule. The ferrule components and/or sleeve are precision formed by high throughput metal stamping. The ferrule is incorporated in an optical fiber connector.

摘要： A compliant structure clamps the alignment pins to accurately and precisely locate the alignment pins. The compliant structure supports the alignment pins with no clearance. The compliant structure is defined by at least a flexure in the form of a cantilevered structure extending at a side of the ferrule. The cantilevered structure, with or without a complementary support structure, defines a space in which an alignment pin can be supported. The flexure may be defined by one or more slots provided on the body of the ferrule to facilitate bending of the extended cantilevered structure. In another embodiment, the ferrule comprises a ferrule insert having grooves for supporting optical fibers, and a ferrule frame that supports the ferrule insert and alignment pins. The compliant structure is provided on the frame. In a further embodiment, the ferrule insert is provided with optical fiber grooves at its perimeter.

摘要： An optical bench subassembly including an integrated photonic device. Optical alignment of the photonic device with the optical bench can be performed outside of an optoelectronic package assembly before attaching thereto. The photonic device is attached to a base of the optical bench, with its optical input/output in optical alignment with the optical output/input of the optical bench. The optical bench supports an array of optical fibers in precise relationship to a structured reflective surface. The photonic device is mounted on a submount to be attached to the optical bench. The photonic device may be actively or passively aligned with the optical bench. After achieving optical alignment, the submount of the photonic device is fixedly attached to the base of the optical bench. The optical bench subassembly may be structured to be hermetically sealed as a hermetic feedthrough, to be hermetically attached to a hermetic optoelectronic package.

摘要： The present invention provides a spring bias that is particularly suited for use to preload a low profile ferrule of an optical connector. In accordance with the present invention, an axial preload is applied to a connector ferrule by a spring structure provided external of the connector. In one embodiment, spring structure is provided outside a plurality of optical fiber connectors, which provides axial preload of multiple ferrules. Each ferrule could be of the type that supports a plurality of optical fibers of a fiber cable. In one embodiment, the spring bias is effected by a planar flexure external of the connector. The ferrule is coupled to the planar flexure with its longitudinal axis through the center of the planar flexure. The planar flexure is structured with flexure members in a plane that are configured to not create any torque load on the ferrule, or if torque loading is present, insignificant torque load to cause misalignment of the ferrule, when the flexure flexes out of its nominal plane to create an axial preload on the ferrule. In another embodiment, a common yoke is applied to bias planar flexures against a plurality of ferrules, wherein a planar flexure is coupled to each ferrule connector. In a further embodiment of the present invention, instead of using planar flexures, a yoke is provided to apply an axial preload to all ferrule connectors coupled to the yoke, by means of a coil spring applied to center of the yoke, external of the ferrule connectors.
