Single photon logic and devices
In this work we use classical metallic plasmonic structures and couple to them quantum dots nano crystals. In this way we increase the dots efficiency using the Purcell effect and demonstrate a directional beaming of photons emitted from the nano crystal. The Bragg cavity modes dominate the emission properties of the quantum dots enabling to achieve special resolution of the emitted photons. We aim to develop a platform for single photon encryption system while both the emitter and detector part will be controlled by electronics.
