Abstract

In this study the analysis of deformation and mode refractive index measurements of H:Ti:LiNbO₃ layers have been investigated. The variations of the lattice parameter in doped layer have been controlled by high-resolution X-ray diffraction measurements. It has been shown that the presence of Ti greatly impacts on crystal lattice deformation induced by subsequent doping by hydrogen. The stability of H:Ti:LiNbO₃ waveguides has been investigated by the high temperature phase freezing by quenching and relaxation to equilibrium phase at room temperature. The variation of the lattice parameter in H:Ti:LiNbO₃ layer appears to be smaller then that in H:LiNbO₃ layer formed at the same conditions.
