Özet

KABUL EDİLDİ


This work focuses on the study of the paraxial wave model with space-time fractional form. This model has more importance for describing light propagation in nonlinear optical fibers and telecommunication lines. The main aim of this work is to observe the effect of fractional parameters effect and compare the truncated -fraction with beta-fraction, conformable fraction form, and classical form of the PW model. For this observation, we applied the Simplest Equation techniques to the acquisition of analytical solutions to the space-time (spatial-temporal) -fractional paraxial wave model. We are able to acquire some new optical soliton solutions, including periodic waves, kink-type waves, rogue-type waves, and some novel periodic waves, by providing the appropriate fractional parametric values. These solutions have significance for shedding light on a number of physical phenomena in the realms of optical fiber and communication sciences. The diverse values of fractional parameters and the three-dimensional and contour plot graphs of certain chosen solutions are depicted, which are the most accurate physical characterizations of the outcomes. We also sketch the comparative graph of diverse fractional forms and the classical form of the paraxial wave equation in two-dimensional plots. Consequently, our finding represents an important breakthrough in this complex area and helps further develop our comprehension of the behavior of soliton.
