Abstract: An exemplary liquid crystal display (LCD) (20) includes a plurality of scanning lines (21) that are parallel to each other and that each extend along a first direction, and a plurality of data lines (2) that are parallel to each other and that each extend along a second direction different from the first direction. Each scanning line includes a first sub-line (211), a second sub-line (212), and a plurality of connecting portions (213) electrically connecting between the first and second sub-lines. The scanning lines of the LCD each include the first and second sub-lines connected in parallel. Thus the scanning lines have a low resistance. When scanning voltages flow through the scanning lines, any voltage drop is relatively small, and all TFTs (23) of the LCD connected with a same scanning line can be driven by substantially the same voltage. Therefore, the LCD has improved display performance.

Abstract: An optical system may be formed by including a plurality of discrete protrusions comprising electro-optic material. Each discrete protrusion is electrically and optically isolated from each other. The protrusions further have defined a top face, a bottom face, a first side face or first and second side faces, and front and back faces. A plurality of electrodes are associated with each of the protrusions. The electrodes are capable of inducing an electric field in the electro-optic material for independently modulating one or more light beams which are incident upon one of the faces of the protrusions. In one preferred embodiment, the protrusions are oriented with respect to the one or more light beams such that each of the light beams enters the protrusion and strikes a boundary between first and second portions of the protrusion at an angle and is reflected by total internal reflection when the first portion is electro-optically activated by application of sufficient voltage, but which will pass substantially unreflected through the boundary when the first portion is not electro-optically activated.

Abstract: An arrangement (10) for efficiently generating tunable pulsed laser output at 8-12 microns. The arrangement (10) includes a laser (12), a first optical parametric oscillator (14) of unique design, and a second optical parametric oscillator (22). The first oscillator (14) is constructed with an energy shifting crystal (20) and first and second reflective elements (16) and (18) disposed on either side thereof. Energy from the laser (12) at a first wavelength is shifted by the crystal and output at a second wavelength. The second wavelength results from a secondary process induced by a primary emission of energy at a third wavelength, the third wavelength resulting from a primary process generated from the first wavelength in the crystal. Mirror coatings are applied on the reflective elements (16 and/or 18) for containing the primary emission and enhancing the secondary process. The second optical parametric oscillator (22) then shifts the energy output by the first OPO (14) at the second wavelength to the desired fourth wavelength. In the illustrative embodiment, the first optical parametric oscillator (14) includes an x-cut rubidium titanyl arsenate crystal (20) and the second optical parametric oscillator (22) includes a silver gallium selenide crystal. The first wavelength is approximately 1.06 microns, the second wavelength is approximately 3.01 microns, the third wavelength is approximately 1.61 microns, and the fourth wavelength is in the range of 8-12 microns.

Abstract: A method of linearizing a modulator (1) having two parallel-coupled sub-modulators (2, 3). The complete transmission function of the modulator includes parameters which relate to power division (A, 1-A) of a non-modulated carrier wave (P.sub.in) and a relationship (B) between the activation degree of the sub-modulators (2, 3). The transmission function is simplified and series-expanded with two higher-order terms, each having a respective coefficient. An expression for intermodulation distortion is calculated with the aid of the series-expansion and with control signals (V1, V2) having two or three frequencies. The signs of the coefficients are determined so that the terms having these coefficients will mutually counteract their respective distortion contributions, and limited search regions for the parameters (A, B) are calculated with the aid of the sign-determined coefficients. In accordance with secondary conditions for high electrooptic efficiency and pronounced modulation depth, the distortion level of the modulator is calculated with the aid of the complete transmission function in the search regions.
