“…The interaction of LDSS with external electromagnetic fields gives rise to linear and nonlinear optical (NLO) responses [9–31] which unfold their immense potential in the fields of quantum computation and in laser technology [32–34] . Added to this, above interaction also opens up new vistas of electronic transport and many other significant phenomena revealed through the interplay between the external AC field and the LDSS confinement potential [34–39] .…”

Current study focuses on realizing the role of Gaussian white noise (GWN) and external sinusoidal polychromatic radiation field (PRF) on the time-average excitation rate (TAER) of impurity doped quantum dot (QD). The PRF induces the transfer of electronic population from the ground state to the excited states in course of time-evolution. The PRF has been envisaged to be composed of four component fields that maintain either a prime or a non-prime frequency ratio. GWN couples with the system additively and multiplicatively. The study highlights the role of various physical parameters, presence of noise, mode of application of noise and the features of PRF (amplitude, phase and type of frequency ratio of the components) in shaping the TAER profiles. The TAER profiles have been found to be enriched with steady growth, steady decline, maximization (useful for obtaining large nonlinear optical response), minimization and saturation (the dynamic freezing). The study reveals promising scope of obtaining desired TAER of doped QD by judicious adjustment/regulation of several control parameters which may bear serious technological implications.
