title: Recovery of the refractive-index profile from the wigner distribution of an optical waveguide.
abstract: We propose a new method for the recovery of the refractive-index profile of a single-mode or multimode optical guided structure. We solve the inverse problem using the Wigner distribution and reduce it to the solution of a linear system of equations.
