In 2018 a new type of single photon source (SPS) based on point defects in GaN was discovered, arousing great interest for their operation at room temperature (RT) and in the infrared (IR) telecom range. However, since 2018, no other experimental paper has deepened the study of such sources. This thesis focuses on their study and their...

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...
