Spectroscopy of the D1-transition of cesium by dressed-state resonance fluorescence from a single (In,Ga)As/GaAs quantum dot

S. M. Ulrich, S. Weiler, M. Oster +4

We use a laser-driven single (In,Ga)As quantum dot (QD) in the dressed state regime of resonance fluorescence ($T=4$ K) to observe the four $D_1$-transition lines of alkali atomi…
