Rogue waves in optical fibers in presence of third-order dispersion, self-steepening, and self-frequency shift

摘要

Rogue waves in optical fibers can be mathematically described by the nonlinear Schr?dinger equation and its extensions that take into account third-order dispersion, self-steepening, and self-frequency shift. These equations are integrable in special cases such as the Sasa-Satsuma or the Hirota equations. However, approximate polynomial solutions can also be obtained in cases beyond these integrable ones. We present these solutions and confirm their validity using numerical simulations.
