Abstract

Recently,1 we have discussed anchoring forces and the electric field as new control parameters for negative- positive refraction index tuning in nanosphere dispersed nematic liquid crystal (NDLC). The present study is focused on calculation of the amplitude modulation of the refractive index caused by amplitude variation of anchoring forces and spatial modulation of anchoring forces. Preliminary results indicate that, similarly to case studied earlier,1 refractive index amplitude modulation can be significantly larger as compared with a conventional liquid crystal (LC) system. The inhomogeneous molecular order in nematic liquid crystal (NLC) cells is modelled using Monte Carlo simulations with the Lebwohl-Lasher effective Hamiltonian with the Rapini- Papoular term for anchoring forces.
