Optical solitons in fiber Bragg gratings with cubic–quartic dispersive reflectivity by enhanced Kudryashov's approach

Abstract

This paper employs the enhanced version of Kudryashov's scheme to recover optical soliton solution in fiber Bragg gratings that are considered with five different nonlinear forms. The effect of cubic–quartic dispersive reflectivity is included in the analysis. A full spectrum of solitons have emerged from this integration scheme, for a couple of cases.
