Anisotropic optical absorption in quantum well wires induced by high-frequency laser fields

The linear and nonlinear optical properties of an off-center hydrogenic donor impurity in nanowire superlattices: Comparison between arrays of spherical and cylindrical quantum dots

“…Furthermore, Fig. 7 hand, the nonlinear absorption coefficient rapidly increases with the growth of optical intensity for cases with larger dipole matrix elements [37,43] . Therefore, in study of the optical properties of the system the nonlinear term should be taken into account, especially when the incident optical intensity is comparatively strong.…”

Linear and nonlinear absorption coefficients of spherical two-electron quantum dot

“…Therefore, many authors have studied the binding energies, the effects of electric and magnetic field and other physical properties of oneelectron QD with various size and shapes [1][2][3][4][5][6]. In one-electron QDs, linear and nonlinear absorption coefficients have attracted the attention of researchers both experimentally and theoretically [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], because QDs have the potential for the device applications such as farinfrared photodetectors, laser amplifiers(wavelength 10m), optical memories, light emitting diodes and high-speed electrooptical modulators [26][27][28].…”

Linear and nonlinear optical absorption coefficients of two-electron spherical quantum dot with parabolic potential

“…Confined quantum systems have been one of the most important subjects of investigation. Therefore, due to their fundamental properties and their wide range of technological applications [1], a great deal of theoretical works on these structures has been reported extensively by using different methods like a finite element method [2,3], perturbation [4], density functional [5,6], configuration interaction [7,8], variational [9,10], exact solution [11], quantum genetic algorithm and Hartree-Fock Roothaan method [12] and other methods [13,14]. Understanding of the electronic and optical properties in such structures is important because these properties are strongly affected by the presence of impurity.…”
