Purcell effect in active diamond nanoantennas


We suggest a novel class of active nanoantennas based on diamond nanoparticles with embedded nitrogen-vacancy centres coupled to Mie resonances of nanostructures. We study optical properties of such nanoantennas including the field enhancement and Purcell effect, and demonstrate experimentally enhancement of the fluorescent rate of the emitters due to particles' resonances, compared to nonresonant regime. Our results pave the way towards active dielectric nanophotonics for quantum light sources, bioimaging, and quantum information processing.
