Using a nitrogen-vacancy color center embedded inside the ring resonator as a source of photons, single photon generation and routing at room temperature is observed. Furthermore, we observe a large overall photon extraction efficiency (10%) and high quality factors of ring resonators (3200 for waveguide-coupled system and 12 600 for a bare ring).en-USNitrogen-vacancy (NV) centerdiamondphotonic crystal cavitysingle photon sourcecavity QEDon-chip photonicsJournal Article2014-04-2510.1021/nl204449n
