Room temperature integrated single photon sources based on highly photostable perovskites nanocubes coupled to optical nanofibers

Abstract

We present a full analysis of the optical and quantum properties of highly efficient perovskite nanocubes with increased photostability. These emitters exhibit reduced blinking together with a strong photon antibunching. Moreover, we achieved the coupling of a single perovskite nanocube with a tapered optical nanofiber, a step toward a compact integrated single photon source.
