    • 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.

    • 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.
