Abstract
This work presents a theoretical investigation into the linear and nonlinear optical characteristics of GaAs/Ga1−xAlxAs quantum wells subject to various trigonometric confinement profiles, with particular attention to the influence of confinement geometry, effective well width, and potential depth on the optical response. In order to carry out this investigation, the system’s energy spectrum and associated wave functions are derived numerically by solving the time-independent Schrödinger wave equation within the framework of the effective mass approximation and envelope function formalism. Their optical behavior is then evaluated using the compact density matrix method based on the obtained eigenvalues and eigenfunctions.
