Abstract

In practical applications, the resultant channel waveguide of LiNbO₃ substrate should be efficiently coupled to the single mode fiber. The core shape of single mode fiber is a circular distribution, but that of the conventional Ti:LiNbO₃ channel waveguide is a semi-elliptical distribution. Optical mode patterns of channel waveguide and single mode fiber can not achieve the mode matching conditions. To improve coupling efficiency between channel waveguide and single mode fiber with arbitrary dimensions, the refractive index profiles and associated fundamental mode patterns of buried Ti/Mg:LiNbO₃ channel waveguides are simulated and controlled from fabrication parameters. We have also investigated the dependences of coupling loss on radial and axial offsets.
