Abstract

An inverse scattering approach to modeling single-mode gradient-index (GRIN) planar guided-wave devices is presented. The method involves solving the Gelfand-Levitan-Marchenko integral equation to obtain a refractive index profile which is infinite in extent. The theory is developed to account for truncations of this refractive index profile, illustrating the effects of a finite core width on the propagation constant. Refractive index profiles with symmetric and asymmetric cladding indexes are considered and discussed.<>
