Cubic-quartic optical solitons with Kudryashov's law of refractive index by F-expansions schemes

This work presents cubic-quartic optical soliton solutions to Kudryashov's equation in polarization-preserving fibers. The integration is conducted with F-expansion scheme having four independent forms. This algorithm additionally reveals several other types of solution that includes Jacobi's elliptic functions, Weierstrass elliptic function, trigonometric function solutions as well as complexion solutions.
