Abstract
We report optical waveguiding of a LiNbO3 single−crystal film grown onto a c−plate LiTaO3 substrate by liquid phase epitaxy from a new Li2O−V2O5 flux. A film of about 3−μm thickness supported seven TE and two TM modes. Measurements of the mode indices indicated that the film is a ’’uniform’’ waveguide having constant refractive indices no=2.2884 and ne=2.1914 throughout the film. Attenuation was measured to be 5 and 11 dB/cm for TM and TE, respectively.Keywords
