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

TL;DR: The brightness of the QD fluorescence is greatly enhanced on resonance with the fundamental mode of the cavity, leading to an high extraction efficiency into a lens with numerical aperture of 0.65, and simultaneously exhibiting low multi-photon probability at this collection efficiency.

A broadband tapered nanocavity for efficient nonclassical light emission
TL;DR: The design of a tapered nanocavity is presented, obtained by sandwiching a photonic wire section between a planar gold reflector and a few-period Bragg mirror integrated into the tapered wire, which largely enhances the spontaneous emission rate of an embedded quantum dot while offering a wide operation bandwidth.

Full counting statistics of quantum dot resonance fluorescence
TL;DR: In this article, an analysis of resonance fluorescence fluctuations based on photon counting statistics is presented, which captures the underlying time-averaged electric field fluctuations of the local environment and maps the environment dynamics directly onto the fluorescence under resonant excitation.

TL;DR: In this paper, the exact arrival time of a single photon as well as the excitation pulse duration were controlled based on resonance fluorescence from a single InAs/GaAs quantum dot, and the effect of the duration of an excitation π pulse on the degree of photon antibunching was investigated.
