Abstract
A method is presented for the experimental determination of refractive -index profiles for planar media of monotonically decreasing refractiv e index, such as those used for optical waveguides. The technique is b ased on a generalization of the classical experiment of Lloyd's mirror , involving the interference pattern formed by a point source and its mirage, i.e., its reflection in such a graded planar medium.
