A GPU-Accelerated Fourth-Order Runge–Kutta in the Interaction Picture Method for the Simulation of Nonlinear Signal Propagation in Multimode Fibers

Abstract: The nonlinear signal propagation in fibers can be described by the nonlinear Schrödinger equation and the Manakov equation. Most commonly, split-step Fourier methods (SSFM) are applied to ...
