Field-Induced and Polymer-Stabilized Two-Dimensional Cholesteric Liquid Crystal GratingsApplied Physics Letters
- Photoinduced Localization,
AbstractThe authors experimentally demonstrate an electrically switchable gratings based on polymer-stabilized, field-induced two-dimensional square-lattice pattern of a cholesteric liquid crystal. A dependence of the two-dimensional diffraction patterns with the magnitude of applied voltage is observed for before and after the polymer stabilization. The diffraction efficiency reaches 84% calculated for the zero order light intensity at the applied voltage of 0.23 V/mu m for a 10 mu m thick sample.
