Optical solutions to the Kundu-Mukherjee-Naskar equation: mathematical and graphical analysis with oblique wave propagation

This paper retrieves some new optical solutions to the Kundu–Mukherjee–Naskar (KMN) equation in the context of nonlinear optical fiber communication systems. In this regard, a complex transformation is applied to the integer-order KMN equation for converting it to an ordinary differential equation (ODE). Then, the generalized Kudryashov method (gKM) and the new auxiliary equation method (NAEM) are employed to the ODE. As consequence, dark,...
