摘要： An optical system includes a light-guide optical element (LOE) (10) having mutually-parallel first and second major external surfaces (11, 12) for guiding light by internal reflection, and a projector (100) that projects illumination corresponding to a collimated image from an aperture (101). The projector injects light in to the LOE via a coupling prism (30) attached to the first major external surface (11) that projects an image injection surface. A reflective polarizing beam splitter (51) is deployed at an interface between the major external surface (11) and the coupling prism (30) parallel to the major external surfaces, to selectively transmit illumination from the coupling prism into the LOE while trapping light already within the LOE so as to propagate within the LOE by internal reflection.

摘要： Color images in electronically switchable reflective displays typically exhibit unsaturated color images due to their low brightness when compared to emissive displays (e.g. OLEDs, LEDs, LCDs). Combining a TIR-based display with a front light system, dynamic light sensor and frame detection system, images may be displayed with saturated colors on a frame-by-frame basis. Ambient light levels may be sensed such that the front light system may emit light in a controlled and minimized manner to substantially maintain the required per frame luminance for highly saturated colors when white subpixels may be dimmed or completely turned off. Such a system will also minimize the use of the power consuming front light system whenever possible. Minimizing light output may conserve energy and optimize battery life.

摘要： The present invention relates to a system and method for input and output optical channel selection. The channels are selected by mirrors generated in specifically structured regions, resulting from selective filling of certain areas with a fluid. In particular, an optical router for switching at least one incident radiation beam towards at least one output, comprises at least one input radiation channel for receiving said radiation beam, at least one switching unit for changing the optical path of the radiation beam, at least one output radiation channel for outputting the deflected radiation. Said switching unit comprises a control unit and at least one fluid/fluid interface mirror that is deformed under the influence of the control unit to deflect the radiation towards a selected output radiation channel, said switching unit further comprising at least one phaseguide structure for mechanically aligning said fluid/fluid interface mirror.

摘要： The invention relates to the field of data processing and communications and can be used for transmitting, receiving and redistributing data signals in switching and encoding and decoding devices in telecommunication systems, communication systems and data processing systems. Essence of the invention: in the multi-channel switch, which optically connects any given optical input channel with any given optical output channel, the bitwise optical connection of the channels is organized in n stages, where n=lg2N is the number of bits, and the connections are carried out in parallel in each bit. At each stage, an operation is performed to double the number of optical channels and an operation is performed to gather the channels, wherein the gathering of the channels is optically controlled as a result of the photorefractive properties of the material of the optical channels. A multi-channel switch is proposed which comprises an active element made from a photorefractive material with waveguide channels, the switching circuit is a cascaded and branching circuit with parallel connection of the optical input and output channels in each cascade, the connection addresses are set with the aid of bars of optical modulators, the number of channels is doubled, and signals are transferred from channel to channel by feeding optical signals of a given configuration to the photorefractive waveguides.

摘要： A display with at least two prism structure types. Type 1 includes prism 16A, color filter FY associated with one prism facet, and control members CC, CM, each biasable with respect to one of the prism's other two facets. Filter FY and members CC, CM have first, second and third spectral absorption characteristics. Type 2 includes prism 16B, color filter FB associated with one of that prism's facets and control member CK1 biasable with respect to one of that prism's other two facets. Filter FB and member CK1 have fourth and fifth absorption characteristics. For any selected set of proximate ones of each prism type, controlled movement of the members between selected combinations of positions causes the whole set to reflect light whose average spectral reflectance corresponds to one of three independent colors, none of which is obtainable by mixing any other two.

摘要： An optical switch (218) is integrated into a planar waveguide substrate in order to selectively switch light (240, 301, 351) entering the switch from one waveguide (232, 234) to exit the switch along either of at least two other waveguides (236, 238). The optical switch (218) includes an electro-optic material (222), preferably PLTZ, that is deposited into a cavity (220) formed within the substrate (214). The switch (218) includes first and second regions (226, 228) that interface at a boundary (230), and the electro-optic material (222) is located in one of the regions (226, 228) such that an electrical field source (212, 213, 224) coupled to the material (222) in the one region (226) adjusts the boundary (230) between transmission and reflection modes. PLTZ is provided in the switch (11) in a formulation that provides little hysteresis with respect to the applied field, and in particular is a non-ferroelectric, cubic, relaxor, polycrystalline, ceramic type having a lanthanum concentration of between about 8.5% and about 9.0%.

摘要： Optoelectronic and photonic devices (100) are formed by employing polymer materials that have a lower glass transition temperature (Tg) than the nominal operating temperature. By using such materials, the local or segmental mobility is increased so that local stress is eliminated or minimized on the polymer material, making performance more robust. The current invention involves use of polymer in an optical device (100) in an operating temperature range in the region above Tg, where the polymer segments between crosslinks are allowed local freedom of movement; however, the large-scale movement of the material may be restricted by the crosslinked structure of the polymer material. The temperature operating point of a device constructed according to the invention is thus preferably distance from both the viscoelastic region near Tg and from the glassy region below Tg.
