Perovskites quantum dots coupled to Mie resonators display an 18-fold luminescence enhancement. Spatially- and time-resolved measurements, coupled to numerical simulations, confirm increased absorption, Purcell factor and extraction efficiency.

The ideal single-photon source displaying high brightness and purity, emission on-demand, mature integration, practical communication wavelength (i.e., in the telecom range), and operating at room temperature does not exist yet. In 2018, a new single-photon source was discovered in gallium nitride (GaN) showing high potential thanks to its...
