Crystal Phase and Orientation Dependence of Electro-Optic Effect in Epitaxial PLZT an PZT Films
Lanthanum-modified lead zirconate titanate and lead zirconate titanate epitaxial films with (100) and (111) orientations were grown respectively on (100) and (111) niobium, lending conductivity to strontium titanate through chemical solution deposition. This study investigated changes in the ordinary and extraordinary refractive index no and ne induced in these films by an electric field using the prism-coupling method. In the (100) epitaxial PZT 30/70 film, anisotropic electro-optic effects arise from the Pockels effect. The isotropic electro-optic effect, which is no = ne , was achieved on (100) epitaxial PLZT 8/65/35 and PZT 70/30 films.
