Abstract. This paper recovers cubic-quartic bright optical solitons with perturbed Fokas–Lenells equation. The Hamiltonian perturbation terms appear with maximal permissible intensity. The semi-inverse variational principle is employed to retrieve such solitons.

Keywords:csoliton, cubic-quartic, perturbation, Fokas–Lenells equation.
