Ferroelectric Tungsten Bronze Bulk Crystals and Epitaxial Thin Films for Electro-Optic Device Applications

Abstract

Several doped and undoped SBN:60 single crystals have been grown by the Czochralski technique. Although the quality of doped crystals needs to be improved, they show a considerable enhancement in electro-optic and photorefractive properties, specifically for Ce(3+)-doped SBN:60 crystals. The addition of these impurity species did not change the growth conditions significantly; however, striations were present and became stronger as the concentration of impurity ions increased. Undoped SBN:60 single crystals have also been grown and they are almost striation-free and exhibit excellent electro-optic properties.
