Abstract
This paper recovers cubic-quartic perturbed solitons in fiber Bragg gratings with quadratic-cubic law nonlinear refractive index. The unified Riccati equation expansion method and the modified Kudryashovâs approach make this retrieval of soliton solutions possible. The parameter constraints, for the existence of such solitons, are also presented.
