abstract = {The paper investigates the soliton dynamics and stability analysis of the time-fractional higher-order nonlinear Schrödinger equation. A Caputo time-fractional derivative is included in the time fractional higher-order nonlinear Schrödinger equation, along with dispersive higher-order and nonlinear terms, which allow us to describe wave propagation in arbitrarily complex nonlinear and dispersive media in greater detail. Through the use of the        ϕ          6      -model expansion method, a vast range of precise analytical soliton solutions is obtained, comprising nonlinear, regular, and singular periodic solitons. The effects of the fractional higher-order physical parameters on the amplitude, width, and nature of these solitons are systematically examined. Moreover, the modulational instability is studied through the use of linear stability analysis. Plots are given in order to explain the change in the form and stability behavior, and the evolution of the soliton solutions as the parameters vary.}
