ZnTe refractive index ellipsoid. The (110) plane in the ZnTe crystal and its coordinate system (X, Y). If no external electric field is applied the crystal is isotropic with refractive index n0. An electric field E (blue arrow), with angle α with respect to the crystallographic X axis, induces the electro-optic effect. The refractive index ellipsoid projected onto the (110)-plane is sketched as an ellipse rotated by Ψ(α) whose main axes, parallel to (U 1 , U 2 ), represent the new refractive indices n1 and n2 of the crystal.
