This work simulates the (1+1)-dimensional nonlinear perturbed Schrödinger model (NLPSM). This model has various applications in mathematical physics and engineering, including hydrodynamics, elastic media, nonlinear optical fiber communication, and plasma physics. There are two primary goals for the study. First, it seeks to find unique soliton solutions such as solitary, dark, periodic, and plane wave solutions that haven’t been found in the literature before using the modified Sardar sub-equation approach (MSSEA). Second, a novel approach to analysis called bifurcation analysis is used to investigate the dynamic behavior of the model. Physical compatibility findings are supported by density, 3-D, and 2-D illustrations made with parametric variables. The analysis shows that the approach used to quickly acquire complete and typical answers was successful. This approach works well for solving challenging problems in physics, engineering, mathematics and fiber optic phenomena.
