| dc.description.abstract | Рассмотрены методы контролируемого возбуждения волноводного распространения света в планарных нематических жидкокристаллических элементах. Продемонстрированы два метода реализации управляемого волноводного режима в нематическом слое жидкого кристалла: 1) электрически контролируемый поляризационно зависимый волноводный режим распространения света в жидкокристаллических элементах с начальной твист-планарной ориентацией директора; 2) индуцированная светом переориентация директора жидкого кристалла, легированного красителем метиловым красным. | ru |

| dc.description.alternative | Methods to control the light beams in planar nematic liquid crystal elements have been considered. The two methods for realisation of the controlled wave-guide mode in a nematic layer of the liquid crystal have been demonstrated. The first method enables one to control the wave-guide light propagation mode in liquid crystal elements with the initial twist-planar orientation of the director. Such orientation makes it possible to realise the polarisation-sensitive mode of the radiation wave-guide propagation in the visible spectral range. The excitation and electric control conditions for the ave-guide mode in the case of polarised laser radiation have been analysed theoretically and tested experimentally. By the second method the wave-guide mode is due to the light-induced director reorientation in the liquid crystal doped with the methyl red dye. The method is based on processes of the anisotropic dye adsorption on one of the bounding surfaces in a liquid crystal cell and on the molecular orientation of the dye under the effect of polarised radiation. The dye molecules act as an orientant for the molecules of the liquid crystal, making it possible to form the local twist-structures whose refractive index for the specific light polarisation is different from that for the nonilluminated region. | ru |
