Post-selected indistinguishable single-photon emission from the Mollow triplet sidebands of a resonantly excited quantum dot

Abstract

Applying high power continuous-wave resonant s-shell excitation to a single self-assembled In- GaAs quantum dot, we demonstrate the generation of post-selected single-indistinguishable photons from the Mollow triplet sidebands. A sophisticated spatial filtering technique based on a double Michelson interferometer enabled us to separate the spectrally close lying individual Mollow components and perform almost background free two-photon interference measurements. Showing high consistency with the results of an independent determination of the emission coherence of 250 +/- 30 ps, our analysis reveals a close to ideal visibility contrast of up to 97 %. Due to their easy spectral tunability and their distinct advantage of cascaded photon emission between the individual Mollow sidebands, they resemble a versatile tool for quantum information applications.
