TLDR
Pulsed resonance fluorescence has been anticipated as the optimum condition for the deterministic generation of high-quality photons with vanishing effects of dephasing and is generated from a single, microcavity-embedded quantum dot under s-shell excitation with 3 ps laser pulses.Abstract:
Pulse-excited resonance-fluorescence single-photons are generated on demand from a single quantum dot embedded in a microcavity under s-shell excitation with an ultrafast laser source.read more

Hai Son Nguyen,Gregory Sallen,Christophe Voisin,Philippe Roussignol,Carole Diederichs,Guillaume Cassabois +5 more
TL;DR: In this article, a novel type of single photon source in solid state, based on the coherent laser light scattering by a single InAs quantum dot, is presented. And the coherence of the emitted single photons is tailored by the resonant excitation with a spectral linewidth below the radiative limit.

Measurement of subpicosecond time intervals between two photons by interference.
TL;DR: A fourth-order interference technique has been used to measure the time intervals between two photons, and by implication the length of the photon wave packet, produced in the process of parametric down-conversion.
