Abstract
Integrated quantum photonics imposes very stringent and oft en contradictory requirements on the design of integrated optical components. Plasmonic materials promise to confer novel properties to integrated quantum devices, that are not achievable with dielectric materials, such as nanoscale footprint, ultrafast operation and very strong light-matter interaction. In this talk, we will focus on the advantages of plasmonics for producing single photons. Our single-photon source is based on a nitrogen-vacancy center in diamond in a gap-plasmon cavity. It features a 200-fold speed-up in emission and a 30-fold increase in detected photon count compared to a reference source made without the plasmonic cavity. We discuss the potential of this enhancement mechanism for the engineering of tomorrow’s quantum photonic systems.
