dc.description.abstractIn this work, we have studied the effects of hydrostatic pressure and an electric field applied along the confinement direction on the absorption coefficient for asymmetric double AlGaAs/GaAs quantum wells within the framework of the effective mass theory. The hydrostatic pressure considered ranges from 0 to 40 kbar, while the chosen electric field ranges from-25 to 30 kV/cm, yielding the most interesting results. We have reported the system's energy levels, the associated dipole matrix elements, and the inter- and intra-band absorption coefficient for the most probable transition, considering each external factor separately. We found that the hydrostatic pressure induces a significant blueshift in the interband absorption coefficient, while it induces a slight redshift in the intraband transitions. On the other hand, the electric field initially redshifts the signal, and later it becomes blue- shifted for the interband absorption coefficient, exhibiting a very similar behavior for intraband transition as the electric field changes. These results show that the hydrostatic pressure, as well as the electric field, can be used as efficient mechanisms to tune both inter and intraband optical transitions.
