    Abstract: A wavelength converter which performs simultaneously wavelength conversion for a plurality of input light wavelengths that are unequally intervals, is provided. The nonlinear material of the wavelength converter has a modulation structure which has modulation of a nonlinear optical constant at a period Λ 0 in a propagating direction of light, a phase being continuously changed each period Λ 0 and a continuous phase modulation for a different period Λ ph being added to the modulation structure. The nonlinear material has a modulation structure obtained by changing a modulation curve for the phase modulation, wherein a phase mismatch Δβ is represented by Δβ = 2π(n 3 /λ 3 - n 2 /λ 2 - n 1 /λ 1 ), and at least three peaks at unequally intervals within a plurality of peaks for conversion efficiency represented by 2π/Λ 0 + 2πi/Λ f (i = m, m+1, ... , n: where m and n are positive or negative integers) have highest conversion efficiency.

    Abstract: L'invention concerne un dispositif de modulation spatiale d'un faisceau lumineux, comprenant un élément à cristal liquide dispersé dans du polymère (PDLC), ledit élément comprenant au moins deux zones pouvant être adressées indépendamment l'une de l'autre au moyen d'un système à au moins deux électrodes (31,32,33,...,411,412,413,...).
    Selon l'invention, lesdites électrodes présentent un motif prédéterminé non rectiligne (31,32,33,...), choisi de façon à réduire la sensibilité à la polarisation dudit dispositif, due à l'apparition d'au moins un champ électrique transverse entre lesdites au moins deux électrodes et ledit dispositif comprend également des moyens optiques de réduction de la sensibilité à la polarisation comprenant au moins une lame à retard de phase anisotrope (44,51).

    Abstract: A liquid crystal display device has a plurality of pixel elements, the optical transmissivity of which is varied by suitable electrical signals. The liquid crystal display device has electrodes which apply electric fields to a liquid crystal layer (50), the electric fields having components in a direction generally parallel to the liquid crystal layer (50). Each pixel element has at least one pixel electrode (1) which extends in a common direction as signal electrodes (12) and common electrodes (2) which extend over several pixel elements. The common electrodes (2) may be on the same side of the liquid crystal layer (50) as the pixel and signal electrodes (1,2), or they may be on opposite sides. Each pixel may have two pixel electrodes (1) with the signal electrode (12) therebetween and there are then a pair of common electrodes (2) with the pixel electrodes (1) therebetween. The common electrodes (2) may be common to adjacent pixel elements. The pixel electrodes (1) and the common electrodes (2) may be separated by an insulating film.
