摘要

本文研究了新的非局部Lakshmanan-Porsezian-Daniel方程的耦合系统。用该模型描述了脉冲在光缆中的传播。本文采用了改进的扩展法。用这种方法可以得到许多解，包括暗孤子解、有理解、周期解、奇异周期解、双曲解、指数解和Jacobi椭圆解。我们通过与现有文献的对比来说明我们发现的波解的独特性和对当前研究的重要补充。一些检索到的解决方案显示图形使用等高线图，2D和3D模型。此外，还比较了几种选择的耦合波解的二维图形。

Innovative optical solitons and other exact wave solutions for coupled system of new nonlocal LPDE using improved modified extended tanh technique

The coupled system of the new nonlocal Lakshmanan–Porsezian–Daniel equation is studied in this manuscript. The pulse propagation in an optical cable is depicted using this model. The improved modified extended tanh method is utilized in this work. Numerous solutions, including dark soliton, rational, periodic, singular periodic, hyperbolic, exponential, and Jacobi elliptic solutions, are offered by this method. We illustrate our discovered wave solutions’ uniqueness and significant addition to current research by contrasting them with the body of existing literature. Some of the retrieved solutions are displayed graphically using contour plots, 2D and 3D models. In addition, a comparison of 2D graphs for a few chosen coupled wave solutions is shown.
