SBN exhibits excellent dielectric non linear properties and one of the largest known Pockels electro-optic coefficient. Thin films of SBN are therefore particularly attractive for their potential use as low voltage electro-optic waveguides or for the realization of electrically-tunable photonic crystals. This chapter proposes an overview of the questions relative to the preparation, dielectric and electro-optic properties of SBN thin films, with a special focus on epitaxial growth in view of electro-optic applications. Experimental results obtained with films prepared by RF magnetron sputtering are presented.
