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: 7269194Abstract: A method and apparatus for driving lasers. An example laser driving system includes a laser current controller for providing a modulation signal and a bias signal. The modulation signal and bias signal is used by a plurality of high-speed current drivers that accept the modulation signal and the bias signal and produce a plurality of laser drive signals. The example system also has a disable input that disconnects power from a high-speed current driver when the high-speed current driver is not in use. The exemplary system develops the modulation and bias signals by feeding back a signal developed from detection of laser light from one of the lasers driven by the system. The laser may be a data laser or a control laser that is modulated by a signal having a lower frequency than the data lasers. If a control laser is used then the photodetector circuit used for feedback can have a lower frequency response because of the lower frequency of the control laser signal.Type: GrantFiled: July 12, 2005Date of Patent: September 11, 2007Assignee: Optical Communication Products, Inc.Inventors: Nelson Diaz, Michael Dudek, Carl Embry

Patent number: 7265439Abstract: An inventive transceiver includes a transmitter for outputting plural beams of electromagnetic energy. In the illustrative embodiment, the transmitter is a vertical cavity surface emitting laser. Plural beams output by the transmitter are directed to the detector by an array of diffractive optical elements. In the preferred embodiment, the optical elements are fabricated by imprinting a pattern on a high temperature film substrate using an ultraviolet epoxy. The use of a vertical cavity surface emitting laser allows for high data rates while the diffractive optical arrangement allows for a compact design.Type: GrantFiled: November 30, 1999Date of Patent: September 4, 2007Assignee: Avago Technologies Fiber IP (Singapore) Pte.

Publication number: 20050261561Abstract: A system and method are provided for determining intravenous blood levels of a target compound contained in a blood vessel of a patient. The method includes the operation of detecting concentrations of the target compound within a patient's blood using a sensor device configured to optically test blood at a location within the blood vessel. Another operation is calculating a measured amount of a therapeutic compound to administer into the patient's bloodstream based on the concentrations of the target compound in the blood. The measured amount of therapeutic compound may then be pumped through the catheter into the patient's blood.Type: ApplicationFiled: May 20, 2005Publication date: November 24, 2005Inventors: Christopher Jones, Carl Embry, Allen Tracy

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.
