Recently, we introduced the concept of a dielectric antenna, which allowed us to demonstrate collection efficiencies from a single emitter in excess of 99% [1][2][3]. Such near-unity collection efficiency paves the way for creating a truly deterministic single photon source, whose inherent statistics is radically different from that of a classical light source. In the present work, we couple a single molecule to a metallo- dielectric antenna and demonstrate sub-poissonian photon statistics. The structure consists of a standard coverglass coated with thin dielectric layers with decreasing refractive indices and a gold mirror. Using standard optics, we are able to measure both high count rates and a noise level below the shot-noise. These experiments bring us one step closer to a perfectly deterministic single photon source that would be highly desirable for information processing and metrology.
