Enhanced single-photon emission from a diamond–silver aperture

Enhanced single-photon emission from a diamond-silver aperture

Solid-state quantum emitters, such as the nitrogen-vacancy centre in diamond1, are robust systems for practical realizations of various quantum information processing protocols2–5 and nanoscale magnetometry schemes6,7 at room temperature. Such applications benefit from the high emission efficiency and flux of single photons, which can be achieved by engineering the electromagnetic environment o...

Enhanced single-photon emission from a quantum dot in a micropost microcavity

We demonstrate a single-photon source based on a quantum dot in a micropost microcavity that exhibits a large Purcell factor together with a small multi-photon probability. For a quantum dot on resonance with the cavity, the spontaneous emission rate is increased by a factor of five, while the probability to emit two or more photons in the same pulse is reduced to 2% compared to a Poisson-distr...

Enhanced Two-photon Emission from a Dressed Biexciton

Bistable Photon Emission from a Solid-State Single-Atom Laser.

We predict a bistability in the photon emission from a solid-state single-atom laser comprising a microwave cavity coupled to a voltage-biased double quantum dot. To demonstrate that the single-atom laser is bistable, we evaluate the photon emission statistics and show that the distribution takes the shape of a tilted ellipse. The switching rates of the bistability can be extracted from the ele...
