Solitary wave solutions of higher-order nonlinear Schrödinger equation with derivative non-Kerr nonlinear terms

Abstract

We present bright and dark solitons induced by the non-Kerr terms in generalized nonlinear Schrödinger equation. The reported solutions consist the Lorentzian-type algebraic solitons. These solitons are of sub 10 femtosecond width and are helpful to increase the information carrying capacity in order to make ultrafast communication, which is useful for transcontinental and trans-oceanic data transfer.
