In a radiative Auger process, optical decay leaves other carriers in excited states, resulting in weak red-shifted satellite peaks in the emission spectrum. The appearance of radiative Auger in the emission directly leads to the question if the process can be inverted: simultaneous photon absorption and electronic demotion. However, excitation of the radiative Auger transition has not been shown, neither on atoms nor on solid-state quantum emitters. Here, we demonstrate the optical driving of… 
Tailoring solid-state single-photon sources with stimulated emissions
The coherent interaction of electromagnetic fields with solid-state two-level systems can yield deterministic quantum light sources for photonic quantum technologies. To date, the performance of
Charge Tunable GaAs Quantum Dots in a Photonic n-i-p Diode
TLDR
This submission discusses the growth of charge-controllable GaAs quantum dots embedded in an n-i-p diode structure, from the perspective of a molecular beam epitaxy grower, and identifies one of the modes as that showing good properties found in previous work.
Harmonizing single photons with a laser pulse
A fast laser pulse stimulates the decay in a quantum dot and suppresses the timing uncertainty in the generation of single photons, which substantially improves the coherence of the source.

TLDR
Self-assembled QDs can serve as an ideal model system to study how the charge recapture process, given by the band-structure surrounding the confined carriers, influences the Auger process, and is identified as the underlying mechanism for the reduced intensity and the broadening of the line width.

It is shown that, like single-atom or single-molecule two- and three-level quantum systems, single semiconductor quantum dots can also exhibit interference phenomena when driven simultaneously by two optical fields.
