For the first time in the field of nonlinear optics, we address cubic–quartic solitons appearing
in the fibre Bragg gratings with dispersive reflectivity for four different cases of nonlinear
refractive-index structures. A complete spectrum of single solitons, together with some
straddled solitons, emerges from the integration scheme adopted by us, which is the
approach of sine–Gordon equation.
