Abstract
This paper recovers cubic–quartic optical solitons for perturbed Fokas–Lenells equation in polarization preserving fibers and birefringent fibers. The perturbation terms appear with maximum permissible intensity. Singular and dark solitons, together with a few combo solitons, emerge from the sine–Gordon equation integration scheme.
