Higher-order Kerr nonlinear and dispersion effects on fiber optics

Abstract

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.
