Singular and Bright soliton solutions for the coupled system corresponding to Gerdjikov-Ivanov equation with four-wave mixing terms

The extended trial function method is utilized in birefringent fibers to generate optical soliton solutions the coupled system that correspond Gerdjikov-Ivanov equation with four-wave mixing terms. approach yields singular and bright solutions, addition extremely important periodic are extracted by taken limit of modulus ellipticity Jacobi’s elliptic function. conditions under which solution exist also provided.
