Characterizing and controlling nanoobjects optically is challenging due to their weak interaction with light. The interaction between matter and light can be amplified, by placing a particle in an optical micro-resonator, due to the Purcell effect. Interfacing a bright material like Perovskite Quantum Dots with an optical cavity gives the possibility to study a highly coherent emitter of single photons. Perovskites exhibit interesting characteristics like a narrow emission line with and high quantum yield. A possible future application is the generation of indistinguishable photons at room temperature, which can later be used in experiments on quantum networks.
