In this paper, we calculated the electronic and optical absorption coefficient of the Manning-like double
quantum well under the external applied electric and magnetic fields. To calculate the linear and thirdorder
nonlinear optical absorption coefficients is used two-level approach in the density matrix expansion.
The findings show that the electronic structure can be adjusted by changing the well and barrier widths, the
well depth, the coupling between the wells as well as applied external field intensities. In addition, direct
and indirect exciton states in asymmetric double quantum wells with Manning-like potential under electric
field are compared with experimental studies. From the obtained results, it is concluded that the Manning-like
potential is an excellent strategy for modeling electronic states in asymmetric double quantum wells with steep
potential barriers and also the Manning-like potential allows modeling interdiffusion effects at the interfaces
of multiple heterostructures.
