Abstract

In the present study, we theoretically study the resonance fluorescence of a two-dimensional quantum dot with parabolic confinement under the effect of Rashba spin–orbit interaction and the magnetic field. We investigate the dependence of the resonance fluorescence and second-order correlation function on the strength of Rashba spin–orbit interaction and the magnetic field has. According to the numerical analyses conducted in this work, location and width of the peaks in the spectrum, as well as the second-order correlation function are modified by the Rashba spin–orbit interaction. In addition, our results show that the presence of magnetic field leads to the strong modification of both the resonance fluorescence spectrum and the second-order correlation function. Overall Rashba spin–orbit interaction and magnetic field can be used for the arbitrary control of the resonance fluorescence characteristics in a quantum dot.
