Linear Optical Beam Translator For Optical Routing
US Patent:
6845187, Jan 18, 2005
Filed:
Sep 8, 2000
Appl. No.:
09/658158
Inventors:
Samuel P. Weaver - Boulder CO, US
Robert T. Weverka - Boulder CO, US
Richard S. Roth - Boulder CO, US
Robert T. Weverka - Boulder CO, US
Richard S. Roth - Boulder CO, US
Assignee:
PTS Corporation - San Jose CA
International Classification:
G02B 626, H04J 1400
US Classification:
385 18, 385 15, 385 16, 385 17, 398 48, 398 49, 398 50, 398 82
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.
Wavelength Router
US Patent:
6501877, Dec 31, 2002
Filed:

Assignee:
Network Photonics, Inc. - Boulder CO
International Classification:
G02B 626
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.
Micromirror Array Having Adjustable Mirror Angles
US Patent:
6600591, Jul 29, 2003
Filed:
Jun 12, 2001
Appl. No.:
09/880230
Inventors:
Robert Anderson - Boulder CO
Bevan Staple - Longmont CO
Richard Roth - 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.
Mems-Based Noncontacting Free-Space Optical Switch
US Patent:
6701037, Mar 2, 2004
Filed:
Jul 3, 2001
Appl. No.:
09/899002
Inventors:
Bevan Staple - Longmont CO
Richard Roth - Boulder CO
Richard Roth - Boulder CO
Assignee:
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.
Switchable Wavelength Add/Drop Component
US Patent:
5946430, Aug 31, 1999
Filed:
Aug 4, 1997
Appl. No.:
8/905515
Inventors:
Alan John Morrow - Elmira NY
Richard Roth - Boulder CO
Richard Roth - Boulder CO
Assignee:
Corning Incorporated - Corning NY
International Classification:
G02B 628
US Classification:
385 24
Abstract:
A device for adding and/or dropping a signal to a transmission line. First and second optical circulators are connected by at least one switchable grating reflector, whereby a grating reflector can be switched into or out of the connecting path between the two circulators. A plurality of optical signals, each centered about a different wavelength, is coupled to a first port of the first circulator; these signals appear at the second port thereof. If a grating reflector capable of reflecting. lambda. sub. i is switched into the circuit, the signal centered about. lambda. sub. i propagates from the second port of the first circulator and reflects from the grating reflector back into the second port and out of the third port. The remainder of the input signals that are not reflected by grating reflectors propagate into the first port and from the second port of the second circulator as an output thereof. Also, a signal at wavelength. lambda. sub.
Transspectral Illumination
US Patent:
7710561, May 4, 2010
Filed:
May 23, 2008
Appl. No.:
12/126078
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.
