Silicon Optical Bench Oct Probe For Medical Imaging
US Patent:
8515221, Aug 20, 2013
Filed:
Jan 25, 2010
Appl. No.:
12/693181

Assignee:
Axsun Technologies, Inc. - Billerica MA
International Classification:
G02B 6/26
US Classification:
385 31
Abstract:
An optical probe for emitting and/or receiving light within a body comprises an optical fiber that transmits and/or receives an optical signal, a silicon optical bench including a fiber groove running longitudinally that holds an optical fiber termination of the optical fiber and a reflecting surface that optically couples an endface of the optical fiber termination to a lateral side of the optical bench. The fiber groove is fabricated using silicon anisotropic etching techniques. Some examples use a housing around the optical bench that is fabricated using LIGA or other electroforming technology. A method for forming lens structure is also described that comprises forming a refractive lens in a first layer of a composite wafer material, such as SOI (silicon on insulator) wafers and forming an optical port through a backside of the composite wafer material along an optical axis of the refractive lens. the refractive lens is preferably formed using grey-scale lithography and dry etching the first layer.

Mechanically Balanced Optical Membrane Device For Orientation Insensitivity
US Patent:
2013030, Nov 14, 2013
Filed:
May 9, 2012
Appl. No.:

Assignee:
AXSUN TECHNOLOGIES, INC. - Billerica MA
International Classification:
G02B 26/08
US Classification:
3592212
Abstract:
An optical membrane device comprises a substrate, at least one support block on a surface of the substrate, and at least one plate. A torsion beam supports the plate above the substrate on the support block. The optical membrane device also includes an optical membrane structure supported by the plate above the substrate and at least one electrode on the substrate underneath the plate. In one implementation, the optical membrane device further comprises a tether for coupling the optical membrane structure to the plate. The tether extends between the optical membrane structure and the plate. In another implementation, the substrate of the optical membrane device has an optical port through the substrate directly below the optical membrane structure. The plate is substantially balanced around the torsion beam to minimize a sensitivity to orientation in a gravitational field.

Assignee:
AXSUN TECHNOLOGIES, INC. - Billerica MA
International Classification:
G02B 27/00
US Classification:
359578
Abstract:
A Fabry-Perot tunable filter comprises a membrane device. The membrane device includes a support structure having an optical port. Also, the membrane device has an optical membrane structure separated from the support structure over the optical port. The optical membrane structure includes a center body portion and an outer body potion. Tethers extend radially from the center body portion to the outer body portion of the optical membrane structure. The center body portion has an area that is about equal or smaller than the area of the optical port.
