摘要

在这项研究工作中，我们使用广义非线性薛定谔方程来研究双幂律介质中的局部波传播，该介质显示出扰动效应，如模态间色散、自频移动和自增强。研究采用了修正扩展映射法（MEMM）。获得了精确解和其他类型的孤子。这些解包括魏尔斯特拉斯椭圆解、奇异周期解以及{亮、暗和奇异}孤子。检索到的解显示了当前方法的鲁棒性和高效性。通过对几个选定解的可视化表示，说明了所建立解的物理属性。

Optical solitons for generalised perturbed nonlinear Schrödinger model in the presence of dual-power law nonlinear medium

We use the generalised nonlinear Schrödinger equation in this research work to study the localised wave propagation in a dual-power law medium that shows perturbations’ effects such as in inter-modal dispersion, shift in the self-frequency, and self-steepening. The modified extended mapping method (MEMM) is used to perform the study. Exact solutions and additional types of solitons are obtained. These solutions include Weierstrass elliptic solutions, singular periodic solutions, and {bright, dark, and singular} solitons. The retrieved solutions show how robust and efficient the current approach is. The physical attributes of the established solutions are illustrated by the visual representation of several selected solutions.
