Effects of external fields on the nonlinear optical properties of an n-type quadruple δ-doped GaAs quantum wells
Linear, third-order, total optical absorption and relative refractive index change coefficients are investigated for an ntype δ-doped GaAs/AlxGa1−xAs quadruple quantum well with electric, magnetic as well as laser fields ... -
Intense terahertz laser field induced electro-magneto-donor impurity associated photoionization cross-section in Gaussian quantum wires
Using expressions derived within the compact density matrix approach, the peaks of optical absorption and the changes of refractive index of a hydrogenic impurity in a GaAs/GaAlAs Gaussian quantum well wire are calculated ... -
Investigation of linear and nonlinear optical absorption coefficients and refractive index changes of a zigzag quantum well with structure parameters and applied external fields
In this study, we have investigated some linear and nonlinear optical properties of GaAs/GaAlAs zigzag quantum well structures under different electric and magnetic field intensities. We also examined the effect of ... -
Nonlinear optical properties in AlxGa1-xAs/GaAs double-graded quantum wells: The effect of the structure parameter, static electric, and magnetic field
