    摘要： One or more lasers are combined with optical energy transfer devices and energy guiding devices which use an electric field for control. The optical energy transfer devices may form gratings, mirrors, lenses and the like using a class of poled structures in solid material. The poled structures may be combined with waveguide structures. Electric fields applied to the poled structures control routing, reflection and refraction of optical energy. Adjustable tunability is obtained by a poled structure which produces a spatial gradient in a variable index of refraction along an axis in the presence of a variable electric field.

    摘要： A new class of energy interaction devices, particularly optical energy transfer devices and energy guiding devices, use an energy field, particularly an electric field, applied to a poled structure to control energy propagation in a solid material. The poled structures, which may form gratings in thin film or bulk configurations, may be combined with waveguide structures to guide energy beams such as optical or acoustic beams. Electric fields applied to the poled structures, such as electrically-activated gratings, control routing of optical energy. Optical devices include but are not limited to, frequency-selective switchable- and adjustably-tunable reflectors, splitters, directional couplers, frequency-tunable switches and efficient beam combiners, as well as polarized beam combiners, am and fm modulators, mode selectors, energy transfer devices, optical data readers, panel display devices, and waveguide/reflector switching arrays. Variable reflectivity in a grating and adjustable tunability is obtained by a poled structure under the influence of an adjustable field, producing a spatial gradient in an adjustable propagation velocity in the solid material.

    摘要： An optical device includes at least a first and second electrical conductors. At least one optical layer overlies at least a portion of the first and second electrical conductors. An applicator is positioned proximate to said at least one optical layer to selectively redirect light from the optical layer. An electrical coupling path between said at least one applicator and one of said first or second electrical conductors, at least a portion of the coupling path traversing said at least one optical layer. At least one optical waveguide may be formed in an optical layer above said electrical conductors. A feature is located to receive light redirected by the applicator and at least one electrical coupling path, which may be included in said feature, couples the applicator and at least one of said plurality of conductors. In a further aspect, a method for manufacturing an optical device is disclosed. The method comprises the steps of: providing a substrate; constructing at least a first electrical conductor in a first substantially planar layer; forming an optical guiding structure in an optical layer; constructing at least one applicator capable of redirecting optical energy; constructing a feature; and electrically coupling said applicator and said at least first electrical conductor.

    摘要： An optical beam routing apparatus is constructed of solid material in which is embedded a beam routing array structure (1370) which has at least a first waveguide segment (1376) traversing the solid material along a plane, second waveguide segments (1378) traversing the solid material along the same plane and encountering the first waveguide segment at a plurality of intersections, electrically-controlled gratings 1372, 1373) disposed transverse to the intersections to controllably reflect optical energy between the first waveguide segment and the second waveguide segments, and optical reflectors (1374, 1375) at selected locations in line with the second waveguide segments (1378) for projecting optical energy into and/or out of the plane from a selected position (1382) on an-out-of-plane medium which might contain optically readable or writable information, such as a disc. Electrodes at the intersections and the electrically-controllable gratings (1372, 1373) disposed transverse of the intersections and controlled by the electrodes controllably reflect optical energy between the first waveguide segment and the second waveguide segment upon application of a controlled electric field at the electrodes.

    摘要： Optical energy transfer devices and energy guiding devices use an electric field to control energy propagation using a class of poled structures in solid material in channel dropping filter and splitter applications. The poled structures, which may form gratings in thin film or bulk configurations, may be combined with waveguide structures. Electric fields applied to the poled structures control routing of optical energy. In a particular embodiment, an electrode confronts a solid material and bridges at least two elements of a grating disposed transverse of two waveguide segments and overlaps evanescent fields of optical energy in one of the waveguide segments. A switchable grating consists of a poled material with an alternating domain structure of specific period. In a further embodiment there may be an optically active cladding between a grating and a waveguide. Additional electrodes may be provided for independent tuning of the cladding and the grating structure. When an electric field is applied across the periodic structure, a Bragg grating is formed by the electro-optic effect, reflecting optical radiation with a certain bandwidth around a center wavelength. The grating may be used by itself, or in combination with other gratings to form integrated structures.
