Growth of LiNbO3 single-crystal film for optical waveguides

Abstract

Ferroelectric LiNbO3 single-crystal film was successfully grown onto a LiTaO3 substrate by a new method, epitaxial-growth-by-melting (EGM) method. The propagation of a He–Ne laser beam fed into the film was demonstrated. Some preliminary results of this new technique for fabricating optical waveguides are reported.
