Patent number: 7331721Abstract: In an exemplary embodiment of the present invention, an optical interface unit provides an interface between an optoelectronic device and industry standard MTP/MPO connectors. The optical interface unit axially aligns the core of a fiber with the optoelectronic device and interfaces that fiber to the standardized connector. In addition, the optical interface unit further provides a standardized interface for visible contact connection between the individual fiber stubs and the terminated fibers in the standardized connector. The optical interface unit therefore maximizes coupling from the optoelectronic device with the standardized connector.Type: GrantFiled: January 8, 2007Date of Patent: February 19, 2008Assignee: Optical Communication Products, Inc.Inventors: Michael Dudek, Michael Tartaglia, Carl Embry, Mark Stiehl, Timothy Bingaman, Steven Anderson, Dale Isaacson

Patent number: 6736553Abstract: A method and apparatus for coupling light from an array of optoelectronic devices to a corresponding array of fibers contained in a fiber optic ferrule is disclosed. The fibers may be single-mode or multi-mode optical fibers. The method includes fixing the fiber optic ferrule to the optical subassembly (OSA) base upon which the array of optoelectronic devices will be affixed, aligning the array of optoelectronic devices to the corresponding array of fibers, then securing the array of optoelectronic devices to the OSA base. In one embodiment, the module includes an optical subassembly module housing a linear array of 1300 nm VCSELs or photodetectors, spaced apart at a 250 micron pitch to correspond to the spacing of optical fibers in a conventional MT ferrule. The array of optoelectronic devices is mounted on a substrate assembly that includes a weldable surface and one or more photodetectors for automatic power control.Type: GrantFiled: January 11, 2002Date of Patent: May 18, 2004Assignee: Optical Communication Products, Inc.Inventors: Mark Stiehl, Michael L.

Patent number: 6709170Abstract: A method and apparatus for encapsulating optoelectronic devices provides for accurately positioning and shaping an encapsulant by actively referencing the device die upon which the optoelectronic devices are formed. A molding tool is accurately aligned to the optoelectronic devices in the x, y and &thgr; directions using mechanical guides and is aligned in the z direction by actively referencing the device die. The shaped encapsulant is preferably an angled wedge having a minimum thickness over the optoelectronic devices to provide a high coupling efficiency and an increased thickness in other portions to fully encapsulate wire bond connections, for example. The method also provides for using the mechanical guides to align and couple optical fibers to the optoelectronic devices. In one exemplary embodiment, the end face of the optical fiber forms a conterminous interface with the top surface of the encapsulant, and the interface is obliquely angled with respect to the surface of the device die.Type: GrantFiled: November 9, 2001Date of Patent: March 23, 2004Assignee: Optical Communications Products, Inc.Inventors: Michael L.

Patent number: 5730729Abstract: An article of manufacture adapted to be connected to a male thread comprises an exterior surface, a cavity opening away from the exterior surface and defining an interior surface, and a plurality of ribs disposed on the interior surface extending longitudinally away from the exterior surface. The article can be connected to the male thread by threading the cavity onto the male thread. It is a particular advantage that the article of this invention, unlike prior art female threaded articles, can be prepared by conventional simple injection molding techniques not requiring an unscrewing step. In one preferred embodiment, the article is a plunger rod intended to be connected to the male threaded post of a plunger of an associated cartridge-needle unit to form a syringe assembly.Type: GrantFiled: June 5, 1995Date of Patent: March 24, 1998Assignee: Sanofi Winthrop Inc.Inventors: William A.
