Abstract

This paper studies Radhakrishnan-Kundu-Laksmannan equation which is used to describe the pulse propagation in optical fiber communications. By using improved modified extended tanh-function method various types of solutions are extracted such as bright solitons, singular solitons, singular periodic wave solutions, Jacobi elliptic solutions, periodic wave solutions and Weierstrass elliptic doubly periodic solutions. Moreover, some of the obtained solutions are represented graphically.

Abstract

In this paper, we apply modified extended direct algebraic method to obtain optical soliton solutions in magneto–optic waveguides with dual-power law nonlinearity. Dark, bright, singular, bright–dark combo and singular-bright combo soliton solutions are obtained. Also, periodic solutions and Jacobi elliptic function solutions are reported. Moreover, for the physical illustration of the obtained solutions, 3D and 2D graphs are presented.
