Abstract

In this paper we report the fabrication of a planar optical waveguide lens on a Y-cut LiNbO₃ substrate by Ti-indiffusion and Ti-indiffused proton-exchange (TIPE). LiNbO₃ planar waveguides are fabricated and refractive indices of the waveguides are measured. Based on the measured indices, planar waveguide lenses are designed and fabricated. The measured focal point and spot size of the fabricated lens are in good agreement with those of the designed lens.
