Spin–orbit interaction effects on the optical rectification of a cubic quantum dot

Optical Rectification and Second Harmonic Generation on Quasi-Realistic InAs/GaAs Quantum Dots: With Attention to Wetting Layer Effect

“…Other studies show that the OR is a function of the applied electric field and confinement strength on QDs [30,32]. In QDs the spin-orbit interaction decreases the magnitude of OR as well as the peaks which happen at lower energies but the donor impurity causes a big shift in the magnitude of the OR peaks position as reported by Chen et al and Vaseghi et al respectively [33,34]. Recently it is found that the OR in lense-shaped QDs is quite sensitive to the applied hydrostatic pressure and temperature [35].…”

“…The effect of size under different values of electric and magnetic fields on SHG for parabolic studied by Li et al [42]; also the length-dependent SHG on cubical QDs as function of incident photon energy was presented by Shao et al [43]. The spin-orbit interaction effects on the OR for different size of QDs were reported by Vaseghi et al [34]. Sabeian and Khaledi-Nasab highlighted the size-dependent intersubband optical properties of dome-shaped InAs/GaAs quantum dots with wetting layer [44].…”

Sum frequency generation in the spherical quantum dots in the presence of applied electric field and spin–orbit interaction

“…Hence, nonlinear optical properties of QDs have been investigated both experimentally and theoretically by many researchers [9][10][11][12]. Fatemidokht and Askari [9] have investigated the impurity and the electric field effects on the SFG process in QDs with parabolic confining potential.…”

“…Li et al [11] have discussed secondharmonic generation (SHG) in parabolic spherical QDs. Vaseghi et al [12] investigated the second-order optical rectification coefficient of a cubic quantum dot with and without Dresselhaus SOI.…”

A theoretical study of nonlinear optical absorption and refractive index changes with the three-dimensional ring-shaped pseudoharmonic potential

“…Therefore, some authors do some researches by adding the number of electrons such as two electrons [9,17,18] and consider polaron [13,[19][20][21] and excitonic [22][23][24] effects. Moreover, the application of an electric field [14,16,18,25], a magnetic field [12,13,26], impurity [10,16,25], spin-orbit interaction [4,27] and external perturbation like hydrostatic pressure [14,16], temperature [14,16] and intense laser field [14,28,29], exhibits novel nonlinear optical phenomena. Besides, changing the confinement potential in quantum structures is a very useful method.…”
