Resonance fluorescence of a quantum dot with acoustically modulated transition energy

I will present experimental and theoretical results that demonstrate the acoustic control of light scattering (resonant fluorescence) on a semiconductor quantum dot (QD). I will discuss the non-linear effects of acoustic frequency mixing in the resonant fluorescence spectrum of a QD modulated by a surface acoustic wave [1]. I will show that the acoustically induced sidebands in the scattering spectrum exhibit characteristic blinking dynamics, which can be further controlled by detuning the laser from the fundamental transition of the QD [2]. In addition, going beyond the current experimental state-of-the-art, I will discuss the acoustic sidebands of the Mollow triplet in the high excitation regime and show how the double dressing of states leads to resonances and suppression of the central line of the spectrum. Finally, I will briefly present our recent results on resonance fluorescence from a randomly modulated system [3].
