Experimental investigation of polarization plane rotation of light in nanoparticle-enriched cholesteric liquid crystal cell with an anisotropic defect layer

The possibility of defect induction controlled by external electric field in nanoparticle enriched cholesteric liquid-crystalline cells with selective reflection in visible range of light and control the rotation of polarization plane of light by induced defect was experimentally demonstrated. The main result of the experiment is the fact that the rotation of the polarization plane of light occurs at lower voltages when the cholesteric liquid crystal is enriched by nanoparticles. A new configuration of liquid crystal device that performs as a tunable linear polarizer for both polarized and unpolarized lights is presented
