Optical solitons with perturbed complex Ginzburg–Landau equation in kerr and cubic–quintic–septic nonlinearity

This paper secures exact solutions from perturbed complex Ginzburg–Landau equation that is taken into account with Kerr law and cubic–quintic–septic nonlinearity. Two approaches are used, namely the trial equation method and complete discriminant system for polynomial method. The abundant exact solutions obtained can better analyze the complex optical phenomena and further demonstrate their essence. •Exact solutions from complex Ginzburg–Landau equation are obtained.•The trial equation method and complete discriminant system for polynomial method are used.•The novelty of this work is that it does not set up constraints in advance for the purpose of integrability like other papers.•These results are more abundant than the existed solutions.
