US Patent:

6496621, Dec 17, 2002

Filed:

Jul 11, 2000

Appl. No.:

09/614184

Inventors:

Alan D. Kathman - Charlotte NC
Charles S. Koehler - Charlotte NC

Assignee:

Digital Optics Corp. - Charlotte NC

International Classification:

G02B 642

US Classification:

385 31, 385 34, 385 89

Abstract:

An apparatus which couples light to a fiber from a light source at an input plane while reducing back reflections includes returning light reflected back through such that the returning light does not substantially overlap with an output of the light source in the input plane. This apparatus may include a mode matching element and/or an angular distribution altering element. The apparatus may be reciprocal. The reciprocal apparatus may prevent light traversing the apparatus again having a change in phase of light from substantially overlapping an original object in an input plane.

International Classification:

G02B 6/42

US Classification:

385 39, 385 33, 385 51

Abstract:

An optical element may include a first diffractive structure having a radially symmetric amplitude function and a second diffractive structure having a phase function. The second diffractive structure may serve as a vortex lens. A system employing the optical element may include a light source and/or a detector.

Assignee:

Tessera North America, Inc. - Charlotte NC

International Classification:

G02B 7/02

US Classification:

359811, 385 24

Abstract:

An optical assembly includes a first transparent substrate having first and second surfaces, a second transparent substrate having substantially parallel third and fourth surfaces, a reflective portion on the second transparent substrate, a plurality of filters between the first substrate and the reflective portion, the plurality of filters filtering light beams incident thereon, the plurality of filters and the reflective portion forming a bounce cavity within the second transparent substrate, a collimating lens for collimating light beams to be input to the bounce cavity, a tilt mechanism for introducing tilt to light beams input to the bounce cavity; an input port receiving light beams and an output port transmitting light beams. The tilt mechanism may be between the first and second substrate.

Filed:

Jul 25, 2006

Appl. No.:

11/492017

Inventors:

Alan Kathman - Charlotte NC, US
John Barnett Hammond - Charlotte NC, US
Robert TeKolste - Charlotte NC, US
Alvaro Cruz Cabrera - Concord NC, US

Assignee:

Tessera North America, Inc. - Charlotte NC

International Classification:

H01S 3/13

US Classification:

372 2901, 372 2902

Abstract:

A wavelength locker for use at more than one wavelength includes filters with different characteristics for a corresponding detector. The filters may be etalons having different free spectral ranges, e. g. , having different apparent or real thicknesses. If more than three such filters are used outputting offset periodic signals, a reference detector may be eliminated and continuous operation over a wavelength range may be realized.

Abstract:

A camera includes a first substrate having a convex refractive element, a second substrate having a concave refractive element, a separation between the first to second substrates, the separation including an air gap between convex refractive element and the concave refractive element, and a third substrate having a detector array thereon, the concave refractive element being closer to the detector than the convex refractive element, at least two of the first to third substrates being secured along a z-axis, wherein the z axis is perpendicular to a plane of the detector array, e. g. , at a wafer level. The convex refractive element may include a plurality of convex refractive elements, the concave refractive element may include a plurality of concave refractive elements, and the detector array may include a plurality of detector arrays, each of the plurality forming a plurality of sub-cameras.
