Optical response in a laser-driven quantum pseudodot system
(ELSEVIER SCIENCE BV, 2017)
We investigate theoretically the intense laser-induced optical absorption coefficients and refractive index changes in a two-dimensional quantum pseudodot system under an uniform magnetic field. The effects of non-resonant, ...
Combined effects of the intense laser field, electric and magnetic fields on the optical properties of n-type double delta-doped GaAs quantum well
(ELSEVIER SCIENCE BV, 2017)
In the present work, the effects of the non-resonant intense laser field, electric and magnetic fields on the optical properties, such as linear, third order nonlinear and the total optical absorption coefficient and ...
Effects of Geometry on the Electronic Properties of Semiconductor Elliptical Quantum Rings
(NATURE PUBLISHING GROUP, 2018)
The electronic states in GaAs-AlxGa1-xAs elliptically-shaped quantum rings are theoretically investigated through the numerical solution of the effective mass band equation via the finite element method. The results are ...
The effects of the electric and magnetic fields on the nonlinear optical properties in the step-like asymmetric quantum well
(ELSEVIER SCIENCE BV, 2014)
In the present work, total optical absorption coefficient (the linear and third-order nonlinear) and total refractive index change for transition between two first lower-lying electronic levels in the step-like GaAs/Ga1-xAlxAs ...
Optical properties of the Tietz-Hua quantum well under the applied external fields
