US Patent:

8553331, Oct 8, 2013

Filed:

Dec 16, 2009

Appl. No.:

12/654316

Inventors:

Jared Stack - Charlotte NC, US
Alan Kathman - Charlotte NC, US

Assignee:

Flir Systems, Inc. - Wilsonville OR

International Classification:

G02B 5/18

US Classification:

359569

Abstract:

A selective diffractive optical element includes a first diffractive region having a first design on a first surface of a substrate, and a second diffractive region having a second design on the first surface of the substrate, the first and second designs being different, wherein, by altering a position of a cross-section of an illumination beam, the selective diffractive optical element outputs a desired proportion of the two diffractive patterns aligned along an optical axis of the illumination beam.

International Classification:

G02B 634
G02B 642

US Classification:

385 14

Abstract:

A passively aligned bi-directional optoelectronic transceiver module assembly utilizes a computer generated hologram as a diffractor to split/combine light beams of two different wavelengths. The entire assembly is constructed of monocrystalline silicon which is photolithographically batch processed to provide a low cost, compact structure with precision tolerances which is inherently passively aligned upon assembly.

Robert A. Boudreau - Hummelstown PA
Hongtao Han - Mechanicsburg PA
John R. Rowlette - Hummelstown PA
Jared D. Stack - Charlotte NC

Assignee:

The Whitaker Corporation - Wilmington DE

International Classification:

G02B 636

US Classification:

385 88

Abstract:

The disclosure describes an optical interconnect which utilizes a silicon waferboard (1) with grooves (3,4) etched to expose preferred crystallographic planes to effect alignment of focusing elements (5) between optical waveguides (6) and optoelectronic devices (2). The focusing elements (5) are made of silicon wafers and are etched to expose crystal planes which compliment crystal planes of cavities or grooves which are etched in the waferboard. The focusing elements may have holograms (7) formed thereon for efficient focusing to the optical waveguide (6).

International Classification:

G02B 628

US Classification:

385 24

Abstract:

A passively aligned optical interconnect is described for use as a wavelength division multiplexer (WDM) and demultiplexer. The device makes use of silicon waferboard for a low cost interconnect. Computer generated holograms are used to effect the multiplexing/demultiplexing as well as focusing of the beams. In an alternative embodiment, the device is used as a beam splitter for monochromatic light. In yet another embodiment, the device is used to spatially separate the polarization states of light.

International Classification:

G02B 27/42
H04B 10/27

Abstract:

An optics system is provided that comprises a glass-based diffractive optical element (DOE) for coupling an optical signal passing out of an optical waveguide into a photodetector. The glass-based DOE improves optical link performance by performing one or more of shortening a response time of a photodetector, preventing an overloading condition of the photodetector from occurring and managing back reflection of light from the photodetector. The glass-based DOE is relatively inexpensively to manufacture and is reliable over a wide range of temperatures.
