Abstract
•Nonlinear analysis approach is used to solve the higher-order nonlinear Schrödinger equations (HONLSEs).•Highly performance and efficient unified solver technique is applied.•Some new solutions of the HONLSEs are obtained.•The results are important in fiber optics applications.
In new communication optical fiber enforcements, the nonlinear Schrödinger equations (NLSEs) have honorable description for soliton transmission characteristics. The NLSEs coefficients such as nonlinear, evolution and dispersion controlled the soliton picture during the fiber transmissions. Sometimes, the dispersive and dissipative fiber materials properties cause the deviations in soliton width-amplitude that obtained from NLSEs. To reduce these effects higher-order nonlinear Schr ödinger equations (HONLSEs) should be investigated. In this work, the unified solver technique is applied in order to solve the HONLSE. The effects of steepness, HO disperion-nonlinear self-frequency have been considered. The higher order effects modified the solitary characteristics in communicating fibers. This investigation is important in new communications soliton handling.
