Abstract EN
We explore the pattern of linear and first nonlinear optical (NLO) response of repulsive impurity doped quantum dots harmonically confined in two dimensions.
The dopant impurity potential chosen assumes Gaussian form.
The quantum dot is subject to a static electric field.
For some fixed values of transverse magnetic field strength (ωc), and harmonic confinement potential (ω0), the influence of impurity strength (V0), impurity stretch (ξ), and impurity location (r0) on the diagonal components of static linear (αxx and αyy), and the first NLO (βxxx and βyyy) responses of the dot are computed through linear variational route.
The investigation reveals the crucial roles played by the various impurity parameters in modulating these optical responses.
Interestingly, maximization in the first NLO responses has been observed for some particular dopant location and at some particular value of spatial stretch of the dopant.
