Appl. No.:

09/880230

Inventors:

Robert Anderson - Boulder CO
Bevan Staple - Longmont CO
Richard Roth - Boulder CO

Assignee:

Network Photonics, Inc. - Boulder CO

International Classification:

G02B 2600

US Classification:

359291, 359223, 359295, 359298, 345108, 345 85, 385 18, 385 14

Abstract:

A method and system are provided for operating an array of such optical micromirrors. Electrodes associated with each of a plurality of optical micromirrors within the array are sequentially actuated by applying a voltage to each such electrode for a fixed time. The voltage applied to each of the electrodes is selected so that the optical micromirror with which that electrode is associated is positioned in a certain tilted position. The step of sequentially actuating electrodes is repeated to maintain the tilted positions of the plurality of optical micromirrors.

PTS Corporation - San Jose CA

International Classification:

G02B 635

US Classification:

385 18

Abstract:

A microstructure for steering light that mitigates stiction problems is provided. A first tiltable assembly that includes a reflective coating is connected with a substrate. A second tiltable assembly is also connected with the substrate. First and second electrodes are connected with the substrate and are configured to tilt the two tiltable assemblies such that they are interdigitated. In various embodiments, the tiltable assemblies are configured as cantilever arrangements and/or torsion-beam arrangements.

Abstract:

An optical routing apparatus that allows flexible and effective routing of optical signals between input and output ports is provided. The apparatus makes use of one or more linearly actuated mirrors, with different routing configurations of the optical signals resulting from different mirror positions. For each such mirror, the linear actuation is may be performed along an axis that is either parallel or perpendicular to the mirror surface.

International Classification:

G02B006/26

US Classification:

385 31, 385 33, 385 39, 385 37

Abstract:

A wavelength router that selectively directs spectral bands between an input port and a set of output ports. The router includes a free-space optical train disposed between the input ports and said output ports, and a routing mechanism. The free-space optical train can include air-spaced elements or can be of generally monolithic construction. The optical train includes a dispersive element such as a diffraction grating, and is configured so that the light from the input port encounters the dispersive element twice before reaching any of the output ports. The routing mechanism includes one or more routing elements and cooperates with the other elements in the optical train to provide optical paths that couple desired subsets of the spectral bands to desired output ports. The routing elements are disposed to intercept the different spectral bands after they have been spatially separated by their first encounter with the dispersive element.

Inventors:

Richard Stefan Roth - Boulder CO, US

International Classification:

G01J 3/40

US Classification:

356302

Abstract:

Methods are disclosed of generating a visible image of an object or scene under study. At least a portion of the object or scene under study is illuminated with light outside a visible portion of an electromagnetic spectrum. Light scattered by the object or scene under study is received. The received light is spectroscopically analyzed for volume elements of the object or scene under study. A respective qualitative feature of the object or scene under study is identified at least one of the volume elements. Visible light is propagated to the at least one of the volume elements according to the respective qualitative feature of the object or scene under study at the at least one of the volume elements.
