Abstract: An illumination system (8) comprises an optical waveguide (18) which is made from optically transparent components and has four end faces (10, 10′). A light source (12) whose light is coupled into the optical waveguide (18) via one of the end faces (10), is situated opposite this end face (10). The optical waveguide (18) has a light guide (30). A number of fibres (34) are attached to a surface (32) of the light guide (30). The fibres (34) have birefringent properties. A preferred method of providing the birefringent properties is to stretch fibres (34) of a suitable polymer plastic material in their longitudinal direction. The light from the light source (12) will be polarized by the fibres (34) and polarised light will be outcoupled from the optical waveguide (18) via an exit surface (16). The illumination system (8) may be used for front or back lightning of LCD panels for e.g. mobile phones, PDA's, etc.

Abstract: The present invention replaces liquid crystal light control elements in fiber-optic faceplate liquid crystal displays (LCD) with suspended particle devices (SPDs), and provides for passive light control without the need for either polarized light or special alignment layers. A fluid or film containing suspended particles may be asymmetric in shape so that their optical density depends strongly upon their orientation. The orientation of the particles within the fluid can be manipulated by an application of an electric field, so that the fluid or film may appear to be transparent to both polarizations of light when the electric field is applied, and opaque when the electric field is removed and the orientation of the particles is allowed to randomize naturally.

Abstract: A programmable dopant fiber includes a plurality of quantum structures formed on a fiber-shaped substrate, wherein the substrate includes one or more energy-carrying control paths, which pass energy to quantum structures. Quantum structures may include quantum dot particles on the surface of the fiber or electrodes on top of barrier layers and a transport layer, which form quantum dot devices. The energy passing through the control paths drives charge carriers into the quantum dots, leading to the formation of “artificial atoms” with real-time, tunable properties. These artificial atoms then serve as programmable dopants, which alter the behavior of surrounding materials. The fiber can be used as a programmable dopant inside bulk materials, as a building block for new materials with unique properties, or as a substitute for quantum dots or quantum wires in certain applications.

Abstract: An optical waveguide (11) includes a region (22) which, after electrical poling of a guiding region (16), maintains an internal electric field induced by the poling potential. The internal electric field may arise from charge separation between regions (18, 20) induced by an adjacent poling electrode (12A), and region (22) acts to inhibit decay of the space charge and to increase the lifetime of the induced electro-optic effect. The waveguide may comprise a twin hole optical fiber (11) with internal electrodes (12A, 14A), where the region (22) comprises a borosilicate layer concentrically disposed about one of the electrodes.

Abstract: An optical waveguide device has a hybrid core and a cladding. A first waveguide having a glass core is coupled to a polymer waveguide disposed adjacent and parallel to the first waveguide such that the respective cores are contiguous in a coupling region. The polymer is a thermo-optically active polymer. A heater is provided over the coupling region and the refractive index of the polymer is varied by applying heat to the region. By application of sufficient heat, the refractive index of the polymer can be changed to approach the refractive index of the cladding whereby the device acts as a simple glass waveguide. In the absence of heat, the device acts as a MMI coupler.
