“…Thus, it goes without saying that the present work examines the TAER from entirely different perspective as it explores the extremely crucial role played by anharmonic potential of different parities which has not been hitherto explored by us. Thus, the present enquiry is absolutely independent of our previous works [64–68] . It needs to be mentioned that, since we are making our studies on the same system, the inherent Hamiltonian defining the system remains the same in all these inspections.…”

“…However, in those studies no dynamical aspects were explored. [64,65] Moreover, very recently, in some other works we have explored TAER among the QD eigenstates triggered by time-dependent noise strength, [66] external PF [67] and external PRF. [68] However, in these studies the presence of anharmonicities in QD confinement potential has not been considered.…”

This work scrutinizes the time-average excitation rate (TAER) among the GaAs quantum dot (QD) eigenstates under the aegis of Gaussian white noise (GWN) and the parity of the anharmonic potential (odd/even). GWN connects with the system by additive or multiplicative mode. The said excitation of the ground state population has been triggered by an external field which may be a polychromatic radiation field (PRF), or pulsed field (PF) or chirped pulsed field (CPF). The study reveals the subtle nuances of the interplay between noise (additive or multiplicative), anharmonicity (odd or even) and the external field (PRF, PF or CPF) that finally govern the attributes of the TAER diagrams. The TAER profiles exhibit persistent growth, persistent decline, maximization (important in view of production of prominent nonlinear optical properties), minimization and saturation (relevant to the dynamic freezing). The findings appear useful for regulating the TAER among the GaAs QD eigenstates which have substantial technological relevance.

Current inspection rigorously explores the tuning of a few relevant nonlinear optical (NLO)properties of GaAs quantum dot (QD) under the stewardship of Gaussian noise-anharmonicity interplay. The NLO properties explored are total optical absorption coefficient (TOAC), total optical refractive index change (TORIC), nonlinear optical rectification (NOR), second harmonic generation (SHG), third harmonic generation (THG), DC-Kerr effect (DCKE), electro-absorption coefficient (EAC), group index (GI)and optical gain (OG). The route of application of noise (additive/multiplicative) to the QD, as well as the symmetry (odd/even) of the anharmonicity, influence the aforesaid NLO properties. These NLO properties exhibit steadfast growth, steadfast fall, maximization, minimization and saturation. The outcomes of the inspection appear to be quite pertinent in the context of the immense technological demand of QD, taking into account the combined impact of anharmonicity and noise.
