Abstract
We explore the pattern of frequency-dependent linear and non-linear optical (NLO) response of electron impurity doped quantum dots harmonically confined in two dimensions. For some fixed values of transverse magnetic field strength ( ω c ), and harmonic confinement potential ( ω 0 ), the influence of impurity location ( x 0 , y 0 ) on the diagonal components of frequency dependent linear ( α xx and α yy ), and the first ( β xxx and β yyy ) NLO responses of the dot is computed through linear variational route. The non-linear polarizabilities undergo maximization at some typical oscillation frequency of the external field depending upon the impurity location.
