Abstract: A liquid crystal display device (10) of the present invention comprises a liquid crystal panel in which a plurality of pixel electrodes (2) are arranged, wherein: shapes of the pixel electrodes (2) are asymmetric, and the pixel electrodes (2) are categorized into plural types whose shapes are different from each other (that is, pixel electrodes A and pixel electrodes B). The liquid crystal panel is configured so that the pixel electrodes of the plural types (that is, pixel electrodes A and pixel electrodes B) are arranged in a regular manner, and the pixel electrodes of the plural types are populated with equal ratios. Thus, in the liquid crystal display device comprising pixel electrodes having a horizontally asymmetric shape viewed from an observer of the liquid crystal panel, a manner in which pixel electrodes of respective types are arranged is changed, thereby improving display quality.

Abstract: The invention relates to an electro-optic directional coupler suitable for use as a variable optical attenuator at reduced voltages compared to those known in the prior art. The present invention has found that by careful selection of an asymmetric directional coupler geometry, the transfer function of the device can be shifted so that it has an operating point between maximum and minimum transmission. Signal electrodes driven in push pull configuration advantageously use this operating point to achieve significant reduction in operating voltages for switching to maximum or minimum transmission. Asymmetry is created in the directional coupler by forming the waveguides to have different propagation constants by a difference in waveguide width, depth, index of refraction or index profile. Asymmetry can alternatively be created by causing mechanical stress in the waveguides through the placement, number, or dimensions of the electrodes, or through asymmetric dielectric structures between the waveguides and the electrodes.

Abstract: A reimagable medium and a method for “writing” to a reimagable medium are disclosed. The reimagable medium includes a liquid crystal layer, one or more photochromic layers and an electric field generating apparatus. The electric field generating apparatus supplies voltage levels across the liquid crystal layer causing the liquid crystal layer to transfer between a white and a transparent state. The photochromic layers transfer to a colored state when illuminated by ultraviolet light and to a transparent state when illuminated by visible light. Each of the layers maintains their present states when voltage or illumination below corresponding thresholds is supplied. The reimagable medium is flexible and may maintain an image “written” to it until the paper is rewritten. The paper may be attached to a colored substrate if an additional color is to be displayed.

Abstract: The invention provides an optical modulator module by which a dip appearing in a frequency characteristic of a microwave from a DC component to a high-frequency component can be reduced while maintaining the mechanical strength and facilitating handling of a substrate and besides securing the long-term reliability without processing the substrate itself. The optical modulator module includes a substrate, an optical modulator including an optical waveguide, a signal electrode, and a ground electrode, and a housing in and to which the optical modulator is accommodated and secured. The shape of a longitudinal section of the other portion of the optical modulator module than the substrate is asymmetrical with respect to a perpendicular line with which the portion of the signal electrode which extends in parallel to the optical waveguide is bisected in the longitudinal direction.

The contoured electric field and/or the poling contour are asymmetric relative to a plane intersecting the waveguide core and extending along the primary axis of propagation. The electrooptic cladding defines at least two cladding regions on opposite sides of the waveguide core. The contoured electric field comprises (i) a vertical electric field component within a first one of said pair cladding regions that is larger than a vertical component in a second one of the cladding regions and (ii) a horizontal electric field component within the first cladding region that is smaller than a horizontal component in the second cladding region.
