An e!cient source of single photons: a single quantum dot in a micropost microcavity
نویسندگان
چکیده
We have used a single quantum dot in a micropost microcavity to generate triggered single photons. Coupling between the quantum-dot dipole and the con8ned microcavity mode leads to a large enhancement of the spontaneous emission rate. This, in turn, leads to e!cient coupling of the emitted photons into a single traveling-wave mode. Optimization of the microcavity design should lead to nearly unity e!ciency, and could also allow for strong coupling and for single-dot lasing. ? 2002 Elsevier Science B.V. All rights reserved.

Efficient source of single photons: a single quantum dot in a micropost microcavity.
We have demonstrated efficient production of triggered single photons by coupling a single semiconductor quantum dot to a three-dimensionally confined optical mode in a micropost microcavity. The efficiency of emitting single photons into a single-mode traveling wave is approximately 38%, which is nearly 2 orders of magnitude higher than for a quantum dot in bulk semiconductor material. At the ...
متن کاملEnhanced 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...
متن کاملCavity-enhanced single photons from a quantum dot
Single-photon sources rarely emit two or more photons in the same pulse, compared to a Poisson-distributed source of the same intensity, and have numerous applications in quantum information science. The quality of such a source is evaluated based on three criteria: high efficiency, small multi-photon probability, and quantum indistinguishability. We have demonstrated a single-photon source bas...
