The behavior of optical soliton solutions in optical fiber theory is described by the Schrödinger–Hirota equation, a nonlinear partial differential equation with multiple applications in science and engineering. In this work, a highly effective approach for solving the Schrödinger–Hirota equation is utilized based on the modified generalized Riccati equation mapping approach. The remarkable achievement of obtaining over one hundred plus newly-formed distinct analytical soliton solutions for the governing Schrödinger–Hirota equation is accomplished through the employment of this technique. The technique employed is characterized by its power, simplicity, and adaptiveness, enabling the extraction of various forms of soliton solutions into a unified framework. As a consequence of the applications, traveling waves, bell-shaped solitons, kink waves, and combo-multisoliton wave profiles are generated. To provide valuable insights into the behavior and characteristics of the solutions, two-dimensional, three-dimensional, and corresponding contour graphs are plotted for selected solutions. These findings contribute to the improvement of theoretical knowledge regarding the Schrödinger–Hirota equation and lay the groundwork for practical implementations. The abundant soliton solutions discovered through this method have the potential to find utility in a variety of fields, including electronics, quantum physics, and optical fibers.

In this work, we proposed a new modified generalized Riccati equation mapping approach to successfully extract several analytical soliton solutions for the (2+1)-dimensional nonlinear Schrödinger (NLS) equation with the help of symbolic computation works in Mathematica.The (2+1)-dimensional NLS equation is used in many fields, including plasma physics, nonlinear optics, and quantum electrodynamics. The main objective of the present work is to develop an effective methodology for solving highly nonlinear evolution equations that are influenced by the enhancement of a previously known method. The approach under consideration is a newly improved version of the classic generalized Riccati equation mapping. By taking advantage of this newly proposed method, we produced a wide range of closed-form solutions, including new optical solitons, traveling waves, and soliton-like solutions, all of which are crucial for nonlinear optics, optical fibers, and the physical propagation of electromagnetic waves. One may clearly argue that the novel method is highly effective and successful in finding exact solutions to nonlinear evolution equations. Moreover, we obtained a variety of new families of soliton-like wave solutions. By using the mathematical software Mathematica, we also created 2D, 3D, and contour graphics for some of the reported solutions by choosing suitable parameter values. [ABSTRACT FROM AUTHOR]
