Polymer-Dispersed Ferroelectric Liquid Crystal Films: Propagation of Polarized Light in the Birefringence Mode

Abstract

On the basis of the amplitude-phase screen model, coherent transmittance for a thin layer of liquid crystal droplets is considered. It is shown that for the polymer dispersed ferroelectric liquid crystal (PDFLC) film produced on the basis of bistable smectic liquid crystals it is possible to provide coherent transmittance close to zero and unity for two stable states of droplet director in the applied field.
