Monte–Carlo simulations of refractive index changes in nematic liquid crystal upon spatially nonuniform illumination (original) (raw)

Optics Communications, 2000

Abstract

We study the influence of a spatially modulated light intensity on the refractive index of a nematic liquid crystal, using Monte–Carlo simulations with a generalized version of the Lebwohl–Lasher hamiltonian. We have considered a model of 2D liquid crystal cell in which one of the electrodes is covered by a photoconducting polymeric layer. The index profiles along the cell thickness are calculated and compared with experimental data.
