Abstract

In this work, we investigate the emission properties of double quantum dot driven by a monochromatic electromagnetic field, while undergoing resonant tunneling and dissipation by phonons. We found emission spectra for both cases, with and without phonons, whose comparison allows to determine the dissipative effects. On the basis of the obtained results we propose efficient control of the resonance fluorescence of an artificial molecule, suitable for optoelectronic applications.
