US Patent:

8520713, Aug 27, 2013

Filed:

Nov 18, 2011

Appl. No.:

13/300531

Inventors:

John R Joseph - Albuquerque NM, US

Assignee:

TriLumina Corporation - Albuquerque NM

International Classification:

H01S 5/00

US Classification:

372 50122, 372 501, 372 75, 372 70, 372 41, 372 22, 372 21

Abstract:

An array of Surface Emitting Laser (SEL) elements can be used to efficiently pump a disk or rod of solid-state laser glass or crystal, or harmonic-generating crystal. Placing the laser array chip against or near the surface of this solid-state material provides very high and uniform optical power density without the need for lenses or fiber-optics to conduct the light from typical edge-emitting lasers, usually formed in a stack of bars. The lasers can operate in multi-mode output for highest output powers. Photolithography allows for an infinite variety of connection patterns of sub-groups of lasers within the array, allowing for spatial contouring of the optical pumping power across the face of the solid-state material. The solid-state material may be pumped either within (intra-cavity) or externally (extra-cavity) to the SEL laser array.

Appl. No.:

13/594714

Inventors:

John R. Joseph - Albuquerque NM, US
Kevin L. Lear - Fort Collins CO, US
David Abell - Albuquerque NM, US

Assignee:

TRILUMINA CORPORATION - Reno NV

International Classification:

H04B 10/11
G02B 27/10
G02B 5/02

US Classification:

398119, 359599, 359619, 398118

Abstract:

High power, high speed VCSEL arrays are employed in unique configurations of arrays and sub-arrays. Placement of a VCSEL array behind a lens allows spatial separation and directivity. Diffusion may be employed to increase alignment tolerance. Intensity modulation may be performed by operating groups of VCSEL emitters at maximum bias. Optical communications networks with high bandwidth may employ angular, spatial, and/or wavelength multiplexing. A variety of network topologies and bandwidths suitable for the data center may be implemented. Eye safe networks may employ VCSEL emitters may be paired with optical elements to reduce optical power density to eye safe levels.

US Patent:

20140079088, Mar 20, 2014

Filed:

Nov 20, 2013

Appl. No.:

14/085686

Inventors:

John R. Joseph - Albuquerque NM, US

Assignee:

Trilumina Corporation - Albuquerque NM

International Classification:

H01S 5/40
H01L 27/15

US Classification:

372 5012, 257 88

Abstract:

Embodiments comprise laser emitter devices that generate a collimated beam of light the intensity or amplitude of which may be varied so as to carry data signals at a high rate of efficiency, and that is less sensitive to alignment of the detector, and detector systems for detecting the same collimated beam and reading the data carried in the beam of light.

John Richard Joseph - Albuquerque NM, US

International Classification:

H04B 10/112
H04B 10/073
H04B 10/116

Abstract:

Techniques are disclosed for aligning an optical transmitter with an optical receiver for a line-of-sight communications link, wherein the optical transmitter comprises a laser array emitter, the laser array emitter comprising a plurality of laser emitting regions, wherein each of a plurality of the laser emitting regions is configured to emit laser light in a different direction such that the laser array emitter is capable of emitting laser light in a plurality of different directions. The system can run produce emissions from different laser emitting regions until a laser emitting region that is in alignment with the optical receiver is found. This aligned laser emitting region can then be selected for use to optically communicate data from the optical transmitter to the optical receiver.
