This numerical study scrutinizes the impact of both the thickness of layers and an externally applied magnetic field on the optical absorption coefficient and alterations in the refractive index pertaining to the intersubband optical transition (1-2) within an asymmetric double parabolic structure, utilizing GaAs/AlGaAs quantum wells as a basis. Energy levels and their corresponding wave functions have been ascertained through the use of the shooting method. The findings of this investigation suggest a pronounced sensitivity of the optical absorption coefficient and changes in the refractive index to the thickness of the layers and the applied external magnetic field. It has been observed that the intensification of the magnetic field results in a resonant peak position shifting towards higher energy values, whereas the thickness of the layers exerts an influence on the resonance peak magnitude. The insights derived from this study hold considerable potential for application, particularly in the development of optical devices predicated on intersubband electronic transitions.

“…It is well known that the basis for the engineering of optoelectronic devices are the intersubband transitions in semiconductor quantum-well structures [3,22,23]. Nowadays, the external effects, in low-dimensional semiconductor quantum well, change the shape of the confinement potential of electrons or holes [24,25]. These external effects in a system such as hydrostatic pressure, electric or magnetic field, and continuous laser radiation changes the intersubband transitions [23].…”

Within the framework of the Thomas-Fermi theory, the electronic structure and the nonlinear optical properties in n-type GaAs double delta-doped quantum wells where determined. In particular, was studied the effects of the distance between the doping layers and the hydrostatic pressure on the absorption coefficient and the change in the refractive index. It was found that the interlayer distance has an important effect on potential geometry, while the pressure lowers the bottom of potential. It was found that the influence of the interlayer distance (hydrostatic pressure) generates a red-shift (blue-shift) on the absorption peak and the refractive index change node. The results indicate that the optoelectronic properties in small interlayer distances (25–50 Å) show a high sensitivity to the changes of hydrostatic pressure, whereas for distances larger than 100 Å the effects of hydrostatic pressure are unimportant for the 1-0 transition. On the far-infrared regime, the effects of these parameters can be applied to tuning the position and amplitude of the resonant optical signals.
