abstract = "In this work we introduce new numerical compact finite-difference algorithms for modeling nonlinear signal propagation in transmission systems based on multimode optical fibers, in the presence of nonlinearity and random linear mode coupling. We compare the computational efficiency of these methods with respect to the standard split-step Fourier method, for different regimes of random mode coupling, such as the weak, the intermediate, and the strong coupling regime. We reveal that, in the intermediate random coupling regime, a non-iterative version of the compact scheme can be twice faster than the standard Fourier method.",

N2 - In this work we introduce new numerical compact finite-difference algorithms for modeling nonlinear signal propagation in transmission systems based on multimode optical fibers, in the presence of nonlinearity and random linear mode coupling. We compare the computational efficiency of these methods with respect to the standard split-step Fourier method, for different regimes of random mode coupling, such as the weak, the intermediate, and the strong coupling regime. We reveal that, in the intermediate random coupling regime, a non-iterative version of the compact scheme can be twice faster than the standard Fourier method.
