Abstract
In this article, the improved modified extended tanh-function method is used to construct new structure of highly dispersive optical solitons for nonlinear Schrödinger equation in birefringent fibers with Kerr law and non-local law of refractive index. Bright solitons, dark solitons, bright–dark combo solitons and singular solitons are obtained. Also, periodic solutions, singular periodic solutions, hyperbolic solutions, rational-type solutions and exponential solutions are reported. After giving suitable values to parameters, the novel structures of solutions are depicted. The physical surfaces of some gained solutions in different forms are shown graphically. The results show the superiority of executed method.
