For this aim, the perturbation Fokas-Lenells equation is converted to a nonlinear ordinary differential equation via wave transformations. Then, the balance number is calculated by the homogeneous balance method. Then, the used methods are applied to the given model. Finally, three-dimensional, contour, and two-dimensional figures of the results are presented. According to the obtained results, both methods are effective and powerful. The obtained results are significant in mathematical physics, soliton theory, and many other areas.eninfo:eu-repo/semantics/closedAccessKundu-eckhaus equationFull nonlinearityConservation-lawsWave solutionsModelFiberDarkPerturbationEnhanced kudryashov?s methodProjective riccati equations methodFokas-lenells equationSolitonsScience & technologyPhysical sciencesOpticsArticle00090641920000127310.1016/j.ijleo.2022.170382
