Phase portrait, bifurcation, chaotic pattern and optical soliton solutions of the Fokas-Lenells equation with cubic-quartic dispersion in optical fibers. (English) Zbl 1520.81083

Summary: The main purpose of this paper is to study the Fokas-Lenells equation with cubic-quartic dispersion describing the propagation of birefringent fibers and polarization preserving fibers. Firstly, using traveling wave transformation and homogeneous balance principle, the Fokas-Lenells equation with cubic-quartic dispersion is simplified into ordinary differential equation. Secondly, the dynamic properties of two-dimensional system and its perturbed system are studied. Finally, by using the trial method of polynomial of rank homogeneous equation, the optical soliton solutions of the Fokas-Lenells equation with cubic-quartic dispersion can be obtained. Moreover, three-dimensional diagram, two-dimensional diagram, density plot and contour plot of the obtained solutions are drawn by explaining the propagation of optical solitons.
