US Patent:

Filed:

Oct 3, 2002
Appl. No.:

10/264533
Inventors:

Sylvain M. Colin - Milpitas CA
Marc A. Finot - Palo Alto CA
Robert M. Kohler - Mountain View CA
Jean-Marc M. Verdiell - Palo Alto CA
Siva M. Yegnanarayanan - Fremont CA
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

G02B 702
US Classification:

359819, 359820, 359822, 359811, 359813, 372101
Abstract:

Modern optoelectronic components have very tight coupling tolerances. Small misalignments of a strong lens that occur during the alignment and bonding process seriously degrade optical coupling. A weak lens is actively mounted using a flexure to correct misalignments of the strong lens. Since the weak lens does not exert as much steering force on a beam for a similar movement as the strong lens, misalignments that may occur during weak lens positioning and bonding do not appreciably degrade coupling.

US Patent:

6838658, Jan 4, 2005
Filed:

Nov 12, 2002
Appl. No.:

10/293140
Inventors:

Sylvain M. Colin - Milpitas CA, US
Raghuram Narayan - Fremont CA, US
Owen B. Pine - Fremont CA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

G01J 350
US Classification:

250226, 372 32
Abstract:

A wavelength locker for monitoring the wavelength drift of a laser uses a pair of detectors for detecting a power component of the laser beam and a wavelength component of the laser beam, respectively. Various positionings of the power detector and/or variations to the collimating lens provide a compact arrangement with fewer components.

US Patent:

6896422, May 24, 2005
Filed:

Feb 4, 2003
Appl. No.:

10/357854
Inventors:

Jeffrey A. Bennett - Sunnyvale CA, US
Pete E. Kirkpatrick - San Francisco CA, US
Sylvain M. Colin - Redwood City CA, US
Jean-Marc Verdiell - Palo Alto CA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

G02B006/36
US Classification:

385 92, 385 88, 385 89, 385 94
Abstract:

Optoelectronic modules and methods of manufacturing the same are disclosed. Some of the disclosed modules employ a tape automated bonding substrate (TAB) which is surface mounted with circuit elements. In some examples, the TAB is mounted to a rigid substrate after a fiber submount is passively positioned on the substrate. This modular manufacturing technique limits the value of yield loss. In some example modules, only one active alignment is employed to manufacture the module. Some of the disclosed modules include an optically pluggable connector.

Filed:

Oct 3, 2002
Appl. No.:

10/264464
Inventors:

Sylvain M. Colin - Milpitas CA, US
Raghuram Narayan - Fremont CA, US
Owen B. Pine - Fremont CA, US
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

H01S003/10
H01S003/13
US Classification:

372 2902, 372 9, 372 32, 372 20, 372 23
Abstract:

Wavelength lockers, which monitor the wavelength drift of a laser's beam due to aging, are tunable to adjust for manufacturing misalignments between its various optical components. Tuning is accomplished by adjusting the position of a collimating lens using a flexure. Adjusting the lens position changes the angle of incidence of a monitored beam relative to a fixed filter and detector and avoids the challenging manufacturing task of rotating the filter and detector to achieve the same result.
