Optical soliton perturbation with full nonlinearity for Gerdjikov–Ivanov equation by trial equation method

This paper obtains optical soliton solution to perturbed Gerdjikov-Ivanov equation by trial equation approach. Bright, dark and singular soliton solutions are derived. Additional solutions such as singular periodic solutions also emerge of this integration scheme.
