Paper Abstract

A polymer wall confined transmissive switchable liquid crystal grating is proposed and investigated by two-dimensional finite-difference time-domain (FDTD) optical calculation and liquid crystal director calculation for the first time. The results show how to get optimized conditions for high diffraction efficiency by adjusting liquid crystal parameters, grating geometric structure and applied voltage. The light propagation direction and efficiency can be accurately calculated as well as visualized at the same time.
