“…2(f). Frequency-resolved correlations for this system have been theoretically investigated in the past [16,[41][42][43][44] and were even measured [13,45,46] before the concept of the 2PS was put forward. But in both theoretical and …”

“…At this point it is worth emphasizing first that both HFS values are of comparable magnitude to or even significantly larger than the observed emission line widths ∆ν of the Mollow triplet components of QD 1 (see Fig. 1(d) According to the theory of dressed state emission [9,11], the frequencies of the triplet [16].…”

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 atomic cesium (Cs) vapor at room temperature. We tune the frequency of the dressing continuous-wave laser in the vicinity of the bare QD resonance ∼ 335.116 THz (∼ 894.592 nm) at constant excitation power and thereby controllably tune the center and side channel frequencies of the probe light, i.e. the Mollow triplet. Resonances between individual QD Mollow triplet lines and the atomic hyperfine-split transitionsare clearly identified in the Cs absorption spectrum. Our results show that narrow-band (In,Ga)As QD resonance fluorescence (RF) is suitable to optically address individual transitions of the D 1 quadruplet without applying magnetic field or electric field tuning.

“…The resulting spectrum, arising from strong resonant pumping, is composed of three lines: a central line, called Rayleigh (R), and two symmetric sidebands called respectively fluorescence (F) and three-photon (T) lines18. The photons emitted in the F and T sidebands have been demonstrated to be highly indistinguishable19, and can also be emitted in a cascaded manner if the QD is specifically pumped20. The splitting of the QD sidebands can be spectrally aligned to the atomic transitions of the Cs hyper fine splitting (that is 9.2 GHz) and their spectral position can be controlled precisely by adjusting the laser power or the QD-to-laser detuning.…”

Simultaneous Faraday filtering of the Mollow triplet sidebands with the Cs-D1 clock transition

Hybrid quantum systems integrating semiconductor quantum dots (QDs) and atomic vapours become important building blocks for scalable quantum networks due to the complementary strengths of individual parts. QDs provide on-demand single-photon emission with near-unity indistinguishability comprising unprecedented brightness—while atomic vapour systems provide ultra-precise frequency standards and promise long coherence times for the storage of qubits. Spectral filtering is one of the key components for the successful link between QD photons and atoms. Here we present a tailored Faraday anomalous dispersion optical filter based on the caesium-D1 transition for interfacing it with a resonantly pumped QD. The presented Faraday filter enables a narrow-bandwidth (Δω=2π × 1 GHz) simultaneous filtering of both Mollow triplet sidebands. This result opens the way to use QDs as sources of single as well as cascaded photons in photonic quantum networks aligned to the primary frequency standard of the caesium clock transition.
