ABSTRACT:
Disclosed herein is an optical waveguide device of LiNbO.sub.3 which guides efficiently both or either of ordinary ray and extraordinary ray of visible light in the short wavelength region. It is prepared by forming an LiNbO.sub.3 thin film optical waveguide on an LiNbO.sub.3 substrate undoped or doped with MgO, with or without a base layer interposed between them, by liquid phase epitaxy which employs Li.sub.2 O-B.sub.2 O.sub.3 as the flux.
