Dark solitons with anti-cubic and generalized anti-cubic nonlinearities in an optical fiber

Abstract

In this research work, anti-cubic and generalized anti-cubic nonlinearity are taken into consideration. The Jacobi elliptic function method and Jacobi elliptic function expansion method is to nonlinear optical fiber for obtaining dark soliton structure. Dark solitons emerged from this method. Furthermore, we establish the physical significance and dynamical behaviors of the dark soliton solutions by using the physical parameter namely dispersion coefficient.
