Strength Added Epoxy Fiber Bonding In Non-Hermetic Fiber Optic Packaging

View page
US Patent:
7083335, Aug 1, 2006
Filed:
Sep 15, 2003
Appl. No.:
10/662595
Inventors:
Rongsheng Miao - Temple City CA, US
Leo Kha - Diamond Bar CA, US
Assignee:
Emcore Corporation - Somerset NJ
International Classification:
G02B 6/36
G02B 6/00
US Classification:
385 92, 385 14, 385 88, 385136
Abstract:
An optical fiber bonding scheme provides improved bonding properties and improved lifetime for non-hermetic fiber optic packages such as OSAs. The bonding scheme includes an optical fiber bonded to a substrate surface with an epoxy and a diffusion retarding plate covering the epoxy. The diffusion retarding plate prevents moisture absorption by the top surface of the epoxy and the large footprint of the epoxy provides a long diffusion path which produces a lower water concentration gradient within the epoxy, restricts lateral diffusion of absorbed water molecules within the epoxy, and produces an extremely saturation resistant epoxy. The diffusion retarding plate may further include legs that bound opposed sides of the epoxy providing further saturation resistance.

Coaxial Cooled Laser Modules With Integrated Thermal Electric Cooler And Optical Components

View page
US Patent:
7118292, Oct 10, 2006
Filed:
Jan 24, 2005
Appl. No.:
11/040915
Inventors:
Rongsheng Miao - El Monte CA, US
Leo Kha - Diamond Bar CA, US
Matthew Swass - Tujunga CA, US
Assignee:
Emcore Corporation - Somerset NJ
International Classification:
G02B 6/42
US Classification:
385 88, 385 93, 385 94
Abstract:
An opto-electric module adapted to be coupled with an optical fiber on a first side and a plurality of electrical conductors on a second side. The opto-electric module includes a header with a plurality of pins extending through the header a thermo-electric cooler with a hot plate of the thermo-electric cooler disposed against a second, opposing side of the header and a plurality of active and passive optical components adapted to convert between an optical signal format within the optical fiber and an electrical signal format within at least one conductor of the plurality of conductors, said plurality of active and passive optical components all being in thermal contact with a cold plate of the thermo-electric cooler.

Photodetector/Optical Fiber Apparatus With Enhanced Optical Coupling Efficiency And Method For Forming The Same

View page
US Patent:
20050053334, Mar 10, 2005
Filed:
Sep 9, 2003
Appl. No.:
10/657836
Inventors:
Rongsheng Miao - Temple City CA, US
Leo Kha - Diamond Bar CA, US
Xin Luo - Monterey Park CA, US
Xiaoming Lou - Arcadia CA, US
International Classification:
G02B006/30
G02B006/42
US Classification:
385049000, 385088000
Abstract:
An optical thick film formed on a photodetector improves the optical coupling efficiency between the optical fiber and photodetector which are optically coupled. The optical thick film has a refractive index that is between the refractive index of air and the refractive index of photodetector upon which the optical matching coating is disposed. Silicone may advantageously be formed as the optical thick film coating on the photodetector.

Bi-Directional Compound-Wdm Fiberoptic System Architecture With Redundancy Protection For Transmission Of Data, Voice And Video Signals

View page
US Patent:
20060291858, Dec 28, 2006
Filed:
Jan 31, 2005
Appl. No.:
11/045914
Inventors:
Xin Lou - Monterey Park CA, US
Leo Kha - Diamond Bar CA, US
International Classification:
H04B 10/20
US Classification:
398058000
Abstract:
An optical architecture and network is described that includes first and second transceivers coupled by an optical fiber. The first and second transceivers concurrently transmit and receive a plurality of optical signals that propagate in a first direction and at least one optical signal propagating in a second, opposite direction through the optical fiber. The network includes the first transceiver that uses a first means for combining the plurality of optical signals and a second means for transmitting the combined plurality of optical signals into the fiber in the first direction and for intercepting and redirecting the optical signal propagating from the fiber in the second, opposite direction. The network further includes the second transceiver that uses a third means for passing the optical signal propagating into the fiber in the second opposite direction and for redirecting the optical signals propagating from the fiber in the first direction. The second transceiver further includes fourth means in a path of the redirected optical signals for passing a first optical signal of the plurality of redirected optical signals and for further redirecting any remaining optical signals and a fifth means for passing a second optical signal of the remaining further redirected optical signals.

Advanced Multi-Gigabit Connectors, Inserts, Active Optical Cables And Methods

View page
US Patent:
20160370547, Dec 22, 2016
Filed:
Jun 17, 2015
Appl. No.:
14/742263
Inventors:
- Glendale CA, US
Leo Kha - Diamond Bar CA, US
Lutz Adrian Mueller - Altadena CA, US
Troy Chase - Pasadena CA, US
Narek Hacopian - Burbank CA, US
Matthew P. Flach - Glendora CA, US
International Classification:
G02B 6/42
H01R 43/16
H01R 13/66
Abstract:
A connector insert arrangement, an active optical cable and methods are described. The connector insert is receivable in a connector housing for removable engagement with a complementary connector. Dielectric inserts each support one or more electrical contacts for access by the complementary connector and each electrical contact is selected as one of a contact pad and a spring probe pin for electrical contact with a complementary spring probe pin and complementary contact pad, respectively, in the complementary connector. A ground body supports the dielectric inserts to maintain a characteristic transmission line impedance along each of a plurality of high speed data paths such that each high speed data path serves as an independent transmission line structure that provides a data transfer rate of at least 1 gigabit per second. An active optical cable is described that can be hermaphroditic.
