This study investigates the nonlinear optical properties of GaAs-based quantum wells (QWs) using a modified Lennard-Jones potential, focusing on the effects of hydrostatic pressure and temperature on various optical coefficients such as total optical absorption, relative refractive index changes, nonlinear optical rectification, second harmonic generation, and third harmonic generation. The Schrödinger equation was solved numerically using the effective mass approximation, and the results reveal the significant influences of pressure and temperature on the nonlinear optical behavior of the system. The analysis demonstrates substantial changes in electron energy levels and state transitions, driven by variations in temperature and pressure. These alterations in energy levels, along with corresponding variations in the dipole moment matrix elements, play a critical role in modifying the optical coefficients. As a result, the study provides valuable insights into the optimization of GaAs quantum wells for improved performance in optoelectronic applications. The findings underline the importance of understanding how thermodynamic parameters affect the nonlinear optical properties, which is essential for optimizing devices such as light-emitting diodes, laser diodes, solar cells, and other quantum well-based technologies. Through comprehensive study of the interplay between pressure, temperature, and the material’s electronic structure, this research contributes to the design and development of advanced quantum well-based devices, offering strategies for enhancing their functionality and efficiency in real-world applications.
