Efficient out-coupling of high-purity single photons from a coherent quantum dot in a photonic-crystal cavity

K. H. Madsen, S. Ates, J. Liu +5

We demonstrate a single-photon collection efficiency of $(44.3\pm 2.1)\%$ from a quantum dot in a low-Q mode of a photonic-crystal cavity with a single-photon purity of $g^{(2)}(0)=…
