Linear and nonlinear optical properties in asymmetric double semi-V-shaped quantum well
(ELSEVIER SCIENCE BV, 2015)
In this present work, the effects of the structure parameters such as the right-well width and the rightbarrier height on the linear, third-order nonlinear and total absorption and refractive index changes of asymmetric ...
Binding energy and optical absorption of donor impurity states in "12-6" tuned GaAs/GaAlAs double quantum well under the external fields
(ELSEVIER SCIENCE BV, 2019)
We have investigated the binding energies of the s-symmetric ground and first excited shallow donor impurity states and the total 1s -> 2s absorption coefficient, including the first and third order corrections, in "12-6" ...
Linear and nonlinear optical properties in a double inverse parabolic quantum well under applied electric and magnetic fields
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2014)
In the present work, the effects of electric and magnetic fields on the optical absorption coefficient and refractive index changes associated with intersubband transitions in a GaAs/AlxGa1-xAs double inverse parabolic ...
Effects of an Intense Laser Field and Hydrostatic Pressure on the Intersubband Transitions and Binding Energy of Shallow Donor Impurities in a Quantum Well
(IOP PUBLISHING LTD, 2011)
We have calculated the intersubband transitions and the ground-state binding energies of a hydrogenic donor impurity in a quantum well in the presence of a high-frequency laser field and hydrostatic pressure. The calculations ...
Effects of magnetic field, hydrostatic pressure and temperature on the nonlinear optical properties in symmetric double semi-V-shaped quantum well

Using a variational approach, we have calculated the donor impurity related photoionization cross-section and impurity binding in GaAs/GaAlAs quantum-well wires under different temperature and hydrostatic pressure conditions. ...
The effects of the intense laser field on the optical properties of the asymmetric parabolic quantum well
(SPRINGER, 2017)
We have calculated the effects of the intense laser field on the total optical absorption coefficient (the linear and third-order nonlinear) for transition between two lower-lying electronic levels in the asymmetric parabolic ...
Combined effects of intense laser field and applied electric field on exciton states in GaAs quantum wells: Transition from the single to double quantum well
(WILEY-V C H VERLAG GMBH, 2012)
The effects of intense laser radiation on the exciton states in GaAs-Ga1xAlxAs quantum wells are studied with the inclusion of applied dc electric fields oriented along the growth direction of the system. The calculations ...
Electronic band structure of GaAs/AlxGa1-xAs superlattice in an intense laser field
