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 Kudryashov’s approach make this retrieval of soliton solutions possible. The parameter constraints, for the existence of such solitons, are also presented
