摘要
A method is presented for calculating the profile of the refractive index of an optical waveguide, n(x) = n(0) + f(x), from the measured coupling angles for any physically justified functional form of f(x). As an example, we present the results of a Ti in-diffused LiNbO(3) waveguide for which f(x) fits the sum of two Gaussians.
