Optical soliton perturbation with resonant nonlinear Schrödinger's equation having full nonlinearity by modified simple equation method

This paper retrieves soliton solutions to the perturbed resonant nonlinear Schrödinger's equation with time-dependent coefficients using the modified simple equation method. The four types of exotic non-Kerr laws studied in this paper are quadratic-cubic law, anti-cubic law, cubic-quintic-septic law and triple-power law. These soliton solutions appear with constraint conditions that guarantee their existence.
