Abstract
In this work the electric field control of diffraction efficiency of holographic polymer dispersed liquid crystal (H-PDLC) film is investigated. It is supposed that H-PDLC film contains ellipsoidal bipolar liquid crystal (LC) droplets. We developed a theoretical model that combines anisotropic coupled-wave theory, Monte-Carlo simulations for director profile within droplet and statistical averaging with the orientational distribution function for droplet symmetry axes. Monte Carlo simulations are done in Lebwohl-Lasher (LL) lattice model supposing strong director tangential anchoring conditions at droplet surface. We calculated diffraction efficiency upon applied voltage for ellipsoidal droplets with different eccentricity and Gaussian orientational distribution function of droplets axes. We investigated diffraction properties of H-PDLC film for both s- and p- light polarizations.
