Paper Abstract

Using x-ray absorption techniques, the Ti center in congruent LiNbO3 is shown to be concentration-dependent. The change in the Ti center takes place within the concentration range used for integrated optics and involves a displacement in the xy plane of the LiNbO3 crystal lattice perpendicular to the polar axis. Reports in the literature indicate that as the ordinary optical index increases with increasing Ti concentration, an abrupt decrease in slope occurs at approximately the same concentration at which our data shows the Ti center itself changes. Simple theory based on a linear-combination-of-atomic-orbitals (LCAO) model suggests that the change in slope of the ordinary index vs Ti concentration can be accounted for by the observed xy displacement of the Ti.
