Patent number: 8260097Abstract: Alignment of one or more lenses with one or more opto-electronic devices in an opto-electronic system is aided by an aligner device having a substantially cylindrical body with a base and an outer ring. The base has one or more openings, one of which is a first opto-electronic device opening. The first opto-electronic device opening has a substantially circular shape coaxial with the outer ring and coaxial with a central axis of the aligner device.Type: GrantFiled: June 16, 2010Date of Patent: September 4, 2012Assignee: Avago Technologies Fiber IP (Singapore) Pte.

Patent number: 8195017Abstract: A consumer input/output (CIO) optical transceiver module, an active optical cable that incorporates a CIO optical transceiver module, and a method for using a CIO optical transceiver module in an active optical cable are provided. In contrast to optical transceiver modules currently used in active optical cables, which utilize parallel arrays of laser diodes and parallel arrays of photodiodes, the CIO optical transceiver module includes two singlet laser diodes and two singlet photodiodes for providing two high-speed transmit channels and two high-speed receive channels, respectively. Because the singlet laser diodes and photodiodes of the CIO optical transceiver module are less costly than the parallel arrays of laser diodes and parallel arrays of photodiodes that are used in known active optical cables, the CIO optical transceiver module can be manufactured at relatively low costs with high quality, and therefore is well suited for consumer applications.Type: GrantFiled: May 31, 2010Date of Patent: June 5, 2012Assignee: Avago Technologies Fiber IP (Singapore) Pte. Ltd.Inventors: Ronald T. Kaneshiro, Xiaozhong Wang, Kit Man Cham, Paul Yu, Chung-Yi Su

Patent number: 8041160Abstract: A parallel optical communications device is provided that has a mounting core that functions as a mounting system for mounting core components of the parallel optical communications device. In addition, the mounting core functions as a heat dissipation system for the core components of the parallel optical communications device, and also protects the core components and other elements of the communications device from dust and damage that can be caused by handling and other factors. In addition to performing the aforementioned functions, the mounting core is configured to enable the parallel optical communications device to be made extremely small in size while also protecting signal integrity.Type: GrantFiled: April 15, 2009Date of Patent: October 18, 2011Assignee: Avago Technologies Fiber IP (Singapore) Pte.

Patent number: 7163343Abstract: An optical module includes an active optical component, an optical fiber, a beam shaping optical component and a positioning device. The optical fiber is arranged with respect to the active optical component to be capable of propagating light along an optical path between the active optical component and the optical fiber. The beam shaping optical component is located in the optical path between the optical fiber and the active optical component. The positioning device is for moving either the beam shaping optical component with respect to the optical fiber, the beam shaping optical component with respect to the active optical component, or the active optical component with respect to the optical fiber, or a combination.Type: GrantFiled: February 10, 2004Date of Patent: January 16, 2007Assignee: Avago Technologies Fiber IP (Singapore) IP Pte.

Patent number: 7021833Abstract: Waveguide based connector systems for optically coupling a fiber optic cable and an optoelectronic device and a method of fabricating the same are described. In one aspect, a connector system comprises an optical waveguide and an optical turn assembly. The optical waveguide has a first end and a second end. The first end of the optical waveguide is connectable to the fiber optic cable in an orientation aligned with a line-side connection axis. The optical turn assembly has a first optical port that is connected to the second end of the optical waveguide in an orientation aligned with a device-side connection axis, a second optical port that is oriented to communicate optically with the optoelectronic device along a device communication axis substantially intersecting the device-side connection axis, and an optical turn system that is operable to guide light along a path between the first optical port and the second optical port.Type: GrantFiled: March 22, 2002Date of Patent: April 4, 2006Inventors: Ban-Poh Loh, James Chang, Pradeep Raj Komar, Brenton A.

Patent number: 6623997Abstract: A submount substrate is used for the dual purposes of enabling simultaneous burn-in processing for a relatively large number of arrays of optical transmitters and enabling conventional dicing techniques to be used to form mounting-ready assemblies. In the preferred embodiment, the submount substrate is a silicon wafer that is specifically designed to provide connectivity between VCSEL arrays and burn-in equipment during the testing stage, but is also designed to be segmented and used in the final packaging stage. Because the submount is a silicon wafer, conventional integrated circuit fabrication techniques may be used to form conductive patterns that define array-receiving areas and that allow external circuitry to communicate with the various VCSEL arrays.Type: GrantFiled: December 15, 2000Date of Patent: September 23, 2003Assignee: Agilent Technologies, Inc.Inventors: James Chang, Ronald T.

Patent number: 5499312Abstract: A method and apparatus for automatic passive alignment of optical waveguides with photonic devices to provide for high volume production of optical components at low cost. The invention includes an optical waveguide having an extremity for transmission of light there through. A first wetable pad is mechanically coupled with the waveguide and is arranged at a selected lateral distance from the extremity of the waveguide. The invention further includes a photonic device having a central region on a surface of the photonic device. A second wetable pad is mechanically coupled with the photonic device and is arranged at a selected lateral distance from the central region of the photonic device. A suitable material, for example solder, is chosen and used in a bond for holding the first pad in alignment with the second pad, so as to substantially provide a desired optical alignment of the extremity of the waveguide with the central region of the photonic device.Type: GrantFiled: August 31, 1994Date of Patent: March 12, 1996Assignee: Hewlett-Packard CompanyInventors: Kenneth H.
