Shu Yang - North Plainfield NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

G02B 0106

US Classification:

359665

Abstract:

A tunable liquid microlens includes an insulating layer, a droplet of a transparent conducting liquid disposed on a first surface of the insulating layer and a plurality of electrodes insulated from the droplet by the insulating layer. The plurality of electrodes are disposed such that they may be selectively biased to create a respective voltage potential between the droplet and each of the plurality of electrodes, whereby a contact angle between the droplet and the first surface is variable and the droplet may be repositioned along the first surface.

Abstract:

A tunable liquid microlens includes an insulating layer, a droplet of a transparent conducting liquid, and a lubricating layer disposed on a first surface of the insulating layer and between the droplet and the insulating layer. The microlens also includes a plurality of electrodes insulated from the droplet by the insulating layer and the lubricating layer, the plurality of electrodes being disposed such that they may be selectively biased to create a respective voltage potential between the droplet and each of the plurality of electrodes, whereby an angle between the droplet and a plane parallel to the first surface of the insulating layer may be varied and the droplet may be repositioned relative to the insulating layer.

US Classification:

359665, 359666, 359299

Abstract:

An apparatus comprising a tunable liquid microlens that includes a transparent supporting layer and a transparent photoresponsive layer disposed on a first surface of the supporting layer. A droplet of a transparent liquid is disposed on the photoresponsive layer. The photoresponsive layer separates the supporting layer and the droplet. At least a portion of the photoresponsive layer that contacts the droplet may be selectively irradiated by at least one light source such that a contact angle between the droplet and the photoresponsive layer may be varied and the droplet may be repositioned along the photoresponsive layer. In this manner, at least one of a focal length and a lateral position of a focal spot of the microlens may be adjusted directly by irradiation with a light beam.

International Classification:

G02B 106

US Classification:

359665

Abstract:

A tunable microlens uses a layer of photo-conducting material which results in a voltage differential between at least one of a plurality of electrodes and a droplet of conducting liquid when a light beam is incident upon the photo-conducting material. Such droplet, which forms the optics of the microlens, moves toward an electrode with higher voltage relative to other electrodes in the microlens. Thus, for example, when the light beam is misaligned with the microlens, the voltage differential causes the droplet, and hence the microlens, to realign itself with the beam.

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

C08G 7706

US Classification:

528480, 528 12

Abstract:

Template-based methods fabricate organosilicate materials with mesoscopic structures. The methods include providing solutions of amphiphilic template molecules, mixing amphiphilic organosilicate precursors into the solutions to form mixtures, and evaporating solvent from the mixtures. The evaporation steps produce composites in which the amphiphilic organosilicate precursors have nontrivial mesoscopic structures.

International Classification:

US Classification:

359665, 359620, 385 41

Abstract:

A tunable microlens is disclosed that having a substrate with a non-zero radius of curvature in a way such that the microlens is able to achieve a new directional view without manual repositioning. The directional view of the microlens is altered by applying a voltage to at least one of a plurality of electrodes and thereby causing a voltage differential between the at least one of a plurality of electrodes and a conducting droplet of liquid disposed on the substrate with a non-zero radius of curvature. As the droplet moves to a different point along the surface of the substrate having a non-zero radius of curvature, the directional view the microlens changes in a way such that light originating from the new directional view is more advantageously focused into an image on a detector. The field of view of the microlens is limited only by the area on the substrate over which the droplet can move. An array of such microlenses may be used to facilitate a wider field of view.

International Classification:

G02B 634

US Classification:

385 37, 385 13

Abstract:

A tunable optical waveguide is enclosed in an enclosure containing a controllably moveable region of fluid with a refractive index greater than the optical fiber such that at least a first transmission property of the waveguide is modified when the region of fluid is moved. In a first embodiment, the optical device comprises a Bragg grating that is tuned by moving the fluid over the grating to vary the amplitude of desired wavelengths that are reflected back through the core of the fiber. In a second embodiment, the optical device comprises a long-period grating that is tuned by moving the fluid over the grating to vary the amplitude of desired wavelengths that are transferred into the cladding of the fiber and, as a result, to decrease the amplitude of those desired wavelengths that are transmitted through the core of the fiber.

Abstract:

A tunable optical lens includes a solid refractive optical lens, a channel adjacent to the solid refractive optical lens, and an extended body of liquid. A portion of the body forms at least part of an aperture stop for the lens. The portion of the body forms a meniscus that protrudes from or into the channel. The liquid is light-absorbing in the visual spectrum and/or in the near-infrared spectrum.
