Construction of solitons in nano optical fibers with dual-power law nonlinearity using MEDAM.

In this study, the generalized nonlinear Schrödinger equation (GNLSE) is examined. This model takes into account the group velocity dispersion, dual-power law nonlinearity and self-frequency shift. This model is used to mimic the wave propagation over nano optical fibers. Studying is conducted by applying the modified extended direct algebraic method (MEDAM). Based on this method, various types of solutions, such as bright solitons, dark solitons, singular solitons, singular periodic solutions, exponential solutions and Weierstrass elliptic solutions are extracted. The extracted solutions confirmed the efficacy and strength of the current technique. Moreover, the graphs for some solutions are presented to demonstrate their physical nature. [ABSTRACT FROM AUTHOR]
