  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.
