Abstract
A method for forming a Luneburg lens having a predetermined focal length on an optical waveguide includes fabricating the lens on a waveguide from a photorefractive material and then exposing the lens to energy radiation, particularly ultra violet light, to thereby adjust the refractive index until the predetermined focal length is established.
