Cavity enhanced characterisation of perovskite quantum dots — •Svenja Müller¹, David Hunger¹, Maksym Kovalenko², Gabriele Raino², and Amrutha Rajan² — ¹Karlsruher Institut für Technologie, Physikalisches Institut, Karlsruhe, Germany — ²ETH Zurich, Department of Chemistry and Applied Biosciences, Zurich, Switzerland

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.
