Abstract
En 中文
In this manuscript, under consideration model is the decoupled nonlinear Schrodinger equation (NLSE) arising in dual-core optical fibers. The NLSEs have become more popular because of the clarity with which they explain a wide range of complex physical phenomena and the depth with which they display dynamical patterns via localized wave solutions. We have secured the optical pulses by the assistance of modern integration tool like the modified extended tanh expansion method. The optical solitons are expressed in the forms of dark, singular and combined optical soliton solutions. In nonlinear dispersive media, optical solitons are stretched electromagnetic waves that maintain their intensity due to a balance between the effects of dispersion and nonlinearity. Moreover, we have secured the hyperbolic, and periodic solutions. The used method not only provides previously extracted solutions but also secures new solutions. Given suitable parameter values, multiple graphs with different shapes are drawn to represent the output in a visual manner. The findings of this study demonstrate that the selected methodologies are efficacious in enhancing nonlinear dynamical phenomena. It is anticipated that a considerable number of engineers that utilize engineering models will find this study to be of interest. The results show that the chosen techniques are effective, easy to implement, and applicable to complex systems in a variety of fields, particularly optical fibers filed. The results suggest that the system possesses a potentially abundant presence of soliton structures.
