Abstract
A waveguide geodesic lens formed in a single-mode Ti-diffused LiNbO 3 waveguide is reported. The paraxial focal length of the geodesic lens fabricated was 1.1 cm. In addition, a novel technique for ultrasonic impact grinding of profiles of arbitrary shape was developed. The paper describes the first single-mode geodesic lens fabricated in a LiNbO3 substrate.
