Regular perturbation for the weak-dispersion regime
Paper i proceeding, 2019
The nonlinear Schrödinger equation (NLSE) takes into account the attenuation, the second order dispersion and the Kerr nonlinearities. No analytical solutions are known, and thus, approximations are required. In this paper, we approximate the NLSE by the regular perturbation on the second order dispersion. With this approximation, it is possible to represent some nonlinear regimes with high accuracy.
