Abstract

Lanthanum-modified lead zirconate titanate and lead zirconate titanate epitaxial films with (100) and (111) orientations are grown respectively on (100) and (111) niobium, lending conductivity to strontium titanate through chemical solution deposition. This study investigates changes in the ordinary and extraordinary refractive index no and ne induced by the electric field in these films using the prism-coupling method. Anisotropic electrooptic effects arise from Pockels effect and switching among polar clusters. Isotropic electrooptic effect is realized on PLZT 8/65/35 and PZT 70/30 of (100) epitaxial films.
