Universal dispersion curves of a planar waveguide with an exponential graded-index guiding layer and a nonlinear cladding
A planar waveguide consisting of three layers is considered. The guiding layer is assumed of exponentially graded index of refraction. The cover layer is a nonlinear material of Kerr-type. The refractive index distribution of the film layer changes as an exponential function from the guiding layer t...
