The resonance spectrum consists of a single spectral line that develops into a triplet above saturation of the quantum emitter. The three closely spaced photon channels from the resonance fluorescence have different photon statistical signatures. We present a detailed photon statistics analysis of the resonance fluorescence emission triplet from a solid-state-based artificial atom, that is, a semiconductor quantum dot. The photon correlation measurements demonstrate both {\textquoteleft}single{\textquoteright} and {\textquoteleft}cascaded{\textquoteright} photon emission from the Mollow triplet sidebands. The bright and narrow sideband emission (5.9 {\texttimes} 106 photons per second into the first lens) can be conveniently frequency-tuned by laser detuning over 15 times its linewidth ({\^I}{\textquoteright}{\textquoteright}v {\textasciitilde} 1.0 GHz). These unique properties make the Mollow triplet sideband emission a valuable light source for quantum light spectroscopy and quantum information applications, for example.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=788), last updated on Wed, 09 May 2012 11:15:12 -0500" }
