“…More recently, some works have been done to build soliton in a nonlinear coupler in a presence of a raman effect and solitary waves in asymmetric tin-core fibers [6,7]. Today, analytical investigation of solitary waves become a big challenge, that is while some relevant methods have been used to construct exact solutions for partial differential equations (PDEs), such as unified method [8,9], initial condition field distributions [10], the simplest equation approach [11], the split-Step method [12], the first integral method [13], new extended direct algebraic scheme [14,15] and the generalized tanh method [16], just to name a few.…”
