Influence of applied external fields on the nonlinear optical properties of a semi-infinite asymmetric AlGaAs/GaAs quantum well
(2021)
The asymmetric potential profiles are of great interest from the nonlinear optical properties point of view for semiconductor devices. The reason for this statement is because the existing theories on nonlinear optical ...
Optical properties of a triple AlGaAs/GaAs quantum well purported for quantum cascade laser active region
(2021)
A theoretical investigation on the conduction electron states in a triple inverse parabolic AlGaAs/GaAs quantum well, designed in the spirit of the active region for a quantum cascade laser, is performed. The study includes ...
Linear and nonlinear optical properties of semi-elliptical InAs quantum dots: Effects of wetting layer thickness and electric field
(Elsevier, 06.06.2022)
In this paper, we have studied the optical properties of semi-elliptical InAs quantum dots (QDs) embedded in GaAs. Under effective mass approximation, the finite element method has been used to obtain wavefunctions and ...
Nonlinear optical properties of modified Möbius squared potential well: influence of electric and magnetic fields
(Taylor & Francis, 2023/11/2)
This work presents a numerical study on the electronic and optical properties of modified Möbius squared potential well in the presence of static electric and magnetic fields. The potential well is formed within GaAs/AlGaAs ...
Effects of external electric and magnetic field on the nonlinear optical rectification, second, and third-harmonic generations in GaAs/AlGaAs asymmetric triple quantum well
(Springer Berlin Heidelberg, 2023/7/31)
In this paper, we theoretically investigate the nonlinear optical rectification (NOR), second-harmonic generation (SHG), and third-harmonic generation (THG) coefficients of an AlGaAs/GaAs asymmetric triple quantum well ...
The nonlinear optical properties of" 12-6" tuned GaAs/GaAlAs double quantum well under the external fields
(Springer Berlin Heidelberg, 2023/2/22)
We have studied the linear and nonlinear optical properties of 12-6 GaAs/Ga1-xAlxAs double quantum well heterostructure under different external fields’ effects such as electric, magnetic and intense laser fields. We also ...
Linear and nonlinear optical properties of CdSe/ZnTe core/shell nanostructures with screened modified Kratzer potential
(Springer Berlin Heidelberg, 2023/4/7)
In this work, we have theoretically examined the linear, nonlinear and total refractive index changes (RICs) and optical absorption coefficients (OACs) between the ground (1s) and the first excited state (1p) of CdSe/ZnTe ...
