Abstract

The refractive indices n and the electro-optical coefficients r of the ZnS and CuAlS₂ materials have been investigated in order to study the birefringence phenomenon induced by the application of an electric field. For the calculation of the electro-optic coefficients r we used the formalism of the density functional perturbation theory DFPT, we obtained for CuAlS_{2 r41} = 0.36 and _r63 = 0.21 Pm / V. We also estimate the half and quarter wave voltages corresponding to phase shift of π and π/2 respectively for the two materials. We have considered the longitudinal E→∥ k→ and transverse E→⊥ k→ propagation modes.
