Notes:
Mg diffusion in Ti-diffused LiNbO3 (Ti/Mg:LiNbO3) optical waveguides has been studied. Secondary ion mass spectrometry has been used to obtain Ti/Mg dopant concentration profiles. Comparison of the diffusion behavior of Mg in pure LiNbO3 and titanium-diffused LiNbO3 (Ti:LiNbO3) has been made. A numerical study, based on semivectorial finite difference method to determine the coupling loss between single-mode fibers and Ti/Mg:LiNbO3 optical waveguides has been performed. It has been demonstrated that the use of Mg can reduce the asymmetry-induced coupling loss to almost zero. A method that predicts the best relative position of the fiber axis with respect to the surface of Ti/Mg:LiNbO3 waveguides has been presented. © 1995 American Institute of Physics.
