Exact Fractional Solution by Nucci’s Reduction Approach and New Analytical Propagating Optical Soliton Structures in Fiber-Optics

Abstract

This study examines the Chen–Lee–Liu dynamical equation, which represents the propagation of optical pulses in optical fibers and plasma. A new extended direct algebraic technique and Nucci’s scheme are used to find new solitary wave profiles. The method covers thirty-seven solitonic wave profiles, including approximately all soliton families, in an efficient and generic manner. New solitonic wave patterns are obtained, including a plane solution, mixed hyperbolic solution, periodic and mixed periodic solutions, mixed trigonometric solution, trigonometric solution, shock solution, mixed shock singular solution, mixed singular solution, complex solitary shock solution, singular solution and shock wave solutions. The exact fractional solution is obtained using Nucci’s reduction approach. The impact of the fractional order parameter on the solution is considered using both mathematical expressions and graphical visualization. The fractional order parameter is responsible for controlling the singularity of the solution which is graphically displayed. A sensitivity analysis was used to predict the sensitivity of equations with respect to initial conditions. To demonstrate the pulse propagation characteristics, while taking suitable values for the parameters involved, 2-D, 3-D, and contour graphics of the outcomes achieved are presented. The influence of the fractional order ζ is shown graphically. A periodic-singular wave with lower amplitude and dark-singular behaviour is inferred from the graphical behaviour of the trigonometric function solution H1 and the rational function solution H34 from the obtained solutions, respectively.

Explicit Soliton Structure Formation for the Riemann Wave Equation and a Sensitive Demonstration

“…PDEs are generally used to create mathematical models of important tangible phenomena in various nonlinear sciences and engineering areas. Nonlinear PDEs have a wide range of practical applications, including mass and heat transportation, continuum mechanics, wave theory, hydrodynamics, chemical technology, acoustics and plasma physics [9][10][11][12][13], biology [14,15], population ecology [16], plasma waves [17], civil engineering [18], quantum mechanics [19][20][21], and so on. In geographical fields, regarding environmental processes induced by energy transportation on floating or synthetic structure fields, waves are primary energy sources.…”

Dynamical features and sensitivity visualization of thin-film Polarisation equation

“…Investigating the solution of such nonlinear equations using other techniques, such as inverse scattering, transform [18], Darboux transform [19], and Tanh method, to mention a few, is important to offer the richness of the solution. Many new recent methods and works can be seen in these [20][21][22][23][24][25][26].…”
