Paper Abstract

The study on optical waveguide geodesic lenses that have no aberration and no singularity in curvature was reported. In theoretical design, the general analytical method for designing a perfect geodesic lens, which was first presented by Sottini et al., was improved. In this paper, a suitable function of meridian in transitional zone was chosen deliberately to make sure that the meridian has a continuous second order derivative. A particular solution of nonsingular in curvature, aberrationless, and non-spherical optical waveguide geodesic lens was presented. This kind of geodesic lenses was designed and fabricated with single point diamond machining and high temperature Ti-diffusing in LiNbO3. Through experimental measurement, it was shown that the spherical aberration was eliminated in 8mm effective aperture and that the focal spot size was 3.3 micrometers for 4.78mm stop size.
