Abstract
When a static electric field is applied to a crystal there are changes in its optical properties. The Pockels effect is a change in the optical dielectric tensor which is proportional to the applied field strength. By generalizing Huang's theory of the linear dielectric properties of an ionic crystal, we have obtained a nonlinear equation for the polarization of a zinc-blende-type ionic crystal. This equation has been used to obtain an expression for the electro-optic coefficient. The calculated values of the electro-optic coefficient for ZnS and CuCl agree satisfactorily with the experimentally determined values.Keywords
