Effects of recording wavelength on three-dimensional vector holograms in photoreactive liquid crystal composites

Accurate transmittance analysis of liquid crystal displays using a rational fraction approach in the time domain

“…The finite-difference time-domain (FDTD) computation [1][2][3] of Maxwell's equations has been widely used as an efficient simulation tool to successfully predict lightwave propagation within liquid crystal (LC) devices [4][5][6][7][8][9]. Here, the FDTD method can simulate the complex anisotropic LCs by considering strong scattering and diffractive effects due to the rapid LC variation as well as spatial inhomogeneties of the LC director orientation, while the commonly used matrix methods are limited by specific types of geometries in modeling anisotropic structures [10,11].…”

Analysis of nonsinusoidal surface relief structures formed by elliptical polarization holography on azobenzene-containing polymeric films

“…1,2) Azobenzene-containing materials have been widely studied as media for polarization holographic recording. [1][2][3][4][5][6][7][8][9][10][11][12] Since azobenzene molecules reorient in accordance with the polarization of light resulting from trans-cis-trans photoisomerization reactions, information on the polarization of light is recorded as a change in the anisotropic refractive index in the medium. In addition, surface relief (SR) deformation is induced on azobenzene-containing polymer (azopolymer) films for holographic recording, and the height of SR deformation depends on the polarization states of the recording beams.…”
