Optical switch based on the electrically controlled liquid crystal interface.

摘要: The peculiarities of the linearly polarized light beam reflection at interface within bulk a nematic liquid crystal (NLC) cell with different orientations director are analyzed. Two methods to create considered. Combination planar and homeotropic NLC is realized by means spatially structured electrode under applied voltage. In-plane patterned azimuthal alignment created rubbing technique. All possible orthogonal LC considered; configurations for realization total internal determined. revealed relationship between propagation optical beams in material polarization laser radiation has enabled spatial separation orthogonally two regions (domains). Owing variations voltage and, hence, refractive index gradient, directions may be controlled electrically.
