Optical soliton perturbation with quadratic-cubic nonlinearity by Riccati-Bernoulli sub-ODE method and Kudryashov's scheme

This paper obtains soliton solutions to the perturbed nonlinear Schrodinger's equation with quadratic-cubic nonlinearity. Two integration algorithms are employed. They are RiccatiBernoulli sub-ODE method and Kudryashov's scheme. This leads to dark, singular and several other forms of soliton solutions that are being reported for the first time in this paper.
