Abstract
The birefringence and electro-optic (EO) effect of barium strontium titanate ((Ba, Sr)TiO3, BST) epitaxial films formed on strontium titanate single crystal substrates were evaluated using a new system employing transmission geometry. The BST films had a strained lattice with a large lattice parameter along the thickness direction. Small birefringence was induced in the as-deposited film by the alignment of the c-axis in the film plane. The birefringence was enhanced by application of electric field before the measurement of the EO-effect. The electric field dependence of the birefringence was a nearly parabolic without a hysteresis shape, indicating that the EO-effect of BST epitaxial film was dominantly determined by the Kerr effect to reduce the birefringence. The Kerr coefficient of the BST film was determined to be 3.44Â ÃÂ 10â17Â m2/V2.
