Abstract
An inverse scattering theory is used to design gradient-index optical waveguides capable of transmitting images without degradation. The propagation characteristics on N modes each carrying a pixel of the image are specified by a transverse rational reflection coefficient. The Gelfand-Levitan-Marchenko inverse scattering theory is used to obtain the unique solution of the permittivity profile of the waveguide from the reflection coefficient.
