Abstract

In this work, a comprehensive analytical investigation of the Lakshmanan–Porsezian–Daniel (LPD) equation is conducted through the application of the Painlevé analysis and the unified method, aimed at constructing exact soliton solutions. Through the application of these analytical tools, explicit forms of soliton solutions are derived with three distinct nonlinear response laws relevant to optical fibers, say, Kerr law, parabolic law, and anti-cubic law, which are associated to various physical regimes and aspects of pulse propagation in nonlinear optical media. For each nonlinearity profile, families of soliton solutions are systematically derived, along with constraint conditions, ensuring their existence, stability, and physical relevance. The novel resulting solutions are then illustrated in three-dimensional surface plots and contour diagrams for suitable parameter values, providing a clearer and more intuitive understanding of the solution dynamics. Finally, a stability analysis of the selected model is performed, confirming that the governing equation exhibits stable behavior under the derived conditions. This study illustrates the versatility of the applied techniques to handle complex nonlinear models, providing rich soliton solutions under various nonlinear laws of optical fibers, and hence contributing to UN Sustainable Development Goals 4, 7 and 9.
不同非线性光学定律下Lakshmanan-Porsezian-Daniel方程中的孤子动力学
本文应用painlev分析和统一方法,对Lakshmanan-Porsezian-Daniel (LPD)方程进行了全面的分析研究,旨在构造精确的孤子解。通过这些分析工具的应用,导出了与光纤相关的三个不同非线性响应定律的显式形式孤子解,即克尔定律,抛物定律和反三次定律,这些定律与非线性光学介质中脉冲传播的各种物理制度和方面有关。对于每个非线性剖面,系统地导出了孤子解族,以及约束条件,确保了它们的存在性、稳定性和物理相关性。然后在三维曲面图和等高线图中说明了新的结果解,为合适的参数值提供了更清晰、更直观的解动力学理解。最后,对所选模型进行了稳定性分析,证实了控制方程在导出的条件下表现出稳定的行为。该研究说明了处理复杂非线性模型的应用技术的多用途性,提供了光纤各种非线性规律下丰富的孤子解,从而有助于实现联合国可持续发展目标4、7和9。
