New private types for the cubic-quartic optical solitons in birefringent fibers in its four forms of nonlinear refractive index

From the point of view extended simple equation method, multiple new private distinct types for cubic-quartic optical soliton birefringent fibers with four forms nonlinear refractive index have been extracted. The suggested model has vital effective effect in all modern telecommunications process. method which invited this purpose examined previously many other problems arising various branches science and continuously gives good results. We will implement to extracting its different NLSE are, polarization-preserving kerr-low nonlinearity, quadratic-cubic law parabolic nonlinearity non-local nonlinearity. Actual comparison between our achieved results that realized by authors established.
