Notes:
Nearly stoichiometric LiNbO3 thin-film waveguides with high crystallinity and good surface morphology were grown on a 5 mol % MgO-doped Z-plate LiNbO3 substrate by liquid phase epitaxy using Li2O-B2O3 flux. The profile of the film-substrate interface was estimated to be nearly a step and a domain inversion with a distinct boundary at the −Z surface of the substrate was observed. Waveguiding was realized for an ordinary wave, but not for an extraordinary wave. There existed no significant optical absorption to the fundamental absorption edge, resulting in a negligibly small propagation loss of less than 1 dB/cm at a wavelength of 458 nm.
