Optical soliton solutions for Kudryashov's quintuple power-law coupled with dual form of non-local refractive index.

The main goal of the article is to present the optical soliton solutions of the nonlinear Schrodinger equation, comprising Kudryashov's quintuple power-law with dual form nonlinearity which has very important applications in domination soliton pulse propagation through optical fibers and photonic crystal fibers. To achieve our goal, two potent analytical techniques are employed: the Sardar-Subequation method and the new method G ′ k G ′ + G + r -expansion method, which represent a novel approach not found in existing literature. Furthermore, our approach offers distinctive solutions characterized by a rich variety of trigonometric and hyperbolic functions. The majority of our results are depicted graphically to highlight our achievements. [ABSTRACT FROM AUTHOR]
