Stationary optical solitons with nonlinear chromatic dispersion having quadratic-cubic law of refractive index

Stationary optical solitons with quadratic-cubic law of nonlinear refractive index and nonlinear chromatic dispersion are retrieved. The model is considered with linear temporal evolution as well as with generalized temporal evolution. The results are in terms of Appell's hypergeometric function whose convergence criteria are also presented. (C) 2020 Elsevier B.V. All rights reserved.
