Double Dressing and Manipulation of the Photonic Density of States in Nanostructured Qubits

Abstract: In this work, a model to study the coupling between a semiconductor qubit and two timedependent electric fields is developed. By using it in the resonantly monochromatic double dressing regime, control of the local density of optical states is theoretically and numerically demonstrated for a strongly confined exciton. Drastic changes in the allowed energy transitions yielding tunable broadening of the optically active frequency ranges, are observed in the simulated emission spectra. The presented results are in excellent qualitative and quantitative agreement with recent experimental observations.
