Accurate impressive optical solitons to the nonlinear refractive index cubic–quartic through birefringent fibers

Abstract

The main target of this work is implementing new accurate impressive optical solitons for four forms of the nonlinear refractive index cubic–quartic through birefringent fibers which play a vital role in all modern telecommunications process. These four different forms have profile names which are the cubic–quartic in polarization-preserving fibers with its different forms which are the Kerr-law, the quadratic-law, the parabolic-law and the non-local-law NLSE. These new accurate optical solitons for these different forms are extracted in the framework of the solitary wave ansatz method which is powerful technique that achieves accurate results for all problems that are solved in the framework of it. The achieved results will be compared by the previous results which are achieved via other authors.
