Nanocrystals on nanolenses: Towards an efficient single photon source at room temperature

Efficient and deterministic single photon emitter devices are an essential resource for quantum cryptography and quantum information transfer. The main challenges are the ability to collect all the photons from the emitter and to reduce the uncertainty in the photon emission time by reducing its emission lifetime.  Of course it would be desired to have such device working at room temperature.

I will review our recent work in which we couple semiconductor nanocrystals, which are single photon emitters, to flat metallic and hybrid metal-dielectric lenses and achieve efficient directional emission of photons, by coupling to either the plasmonic or waveguided optical modes of the antenna.
