In this paper, we aim to derive new soliton solutions of (1 + 1)- and (2 + 1)-dimensional generalized Sasa-Satsuma equations via the new Kudryashov method. In optical fiber transmission systems, the Sasa-Satsuma equation describes the effects of third-order dispersion, self-steepening and stimulated Raman scattering in the propagation of ultra-fast pulses. The considered equations are encountered in various physical applications such as ultra-short and fenao-second pulse propagation in optical fibers and dynamics of deep water waves. So, investigation of the novel solutions of the equations is one of the important topics. We have successfully extracted some soliton solutions for the considered equation. The various graphs of the obtained solutions have been depicted in the figures by selecting appropriate parameters. The singular and bright soliton solutions have been revealed in the figures. All acquired solutions have been confirmed to satisfy the considered equations. The results show that the approach may he used to find exact solutions to various nonlinear evolution equations. The new solutions and the paper results may enrich the understanding of the wave propagation in the optical fibers and may shed light on new studies.
