A single GaAs/GaAsSb/GaAs quantum well having a valence band profile was described in this study using the V-shaped potential. An external static electric field (E-field) and a high-frequency intense laser irradiation were utilized to examine the first-order linear and third-order nonlinear optical properties. The theoretical modeling was achieved using a compact-density matrix and iterative process in a two-level system framework. The position-dependent effective mass approximation was applied to solve the Schrödinger equation and evaluating the energy states and their corresponding wavefunctions for the two lowest bound states within the quantum well's valence band with regards to a heavy hole. We extended the investigation of the single V-shaped potential by incorporating the effects of the E-field, the well's half-width, and antimony (Sb) content on optical characteristics. The study on the combined effects of the intense laser field and the mentioned factors revealed that the peak positions and amplitudes of the linear and nonlinear optical characteristics were strongly influenced by variation in the laser strength. Specifically, we observed, that under higher laser dressing parameters, the application of the electric field played an important role. This occurred when the impact of the well's half-width and Sb content became prominent at values of lower laser-dressing parameters. It is significant to note that our findings will have potential real-world applications in photonics, optoelectronics, and related areas.
