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
