This study addresses the modeling pulse propagation in optical fibers, focusing on a coupled system of nonlinear Schrödinger’s equation for the generalized Kudryashov’s equation in a magneto-optic waveguide. A magneto-optic waveguide is a waveguide that uses the magneto-optic phenomenon to manipulate the movement of light. This phenomenon entails the interplay between a magnetic field and light, which can alter the polarization or orientation of the light wave.
