Publication Coupling of NV Centers to Photonic Crystal Nanobeams in Diamond
(American Chemical Society (ACS), 2013) Hausmann, Birgit Judith Maria; Shields, Brendan John; Quan, Qimin; Chu, Yiwen; de Leon, Nathalie Pulmones; Evans, Ruffin; Burek, Michael; Zibrov, Alexander; Markham, M.; Twitchen, D. J.; Park, Hongkun; Lukin, Mikhail; Loncar, MarkoThe realization of efficient optical interfaces for solid-state atom-like systems is an important problem in quantum science with potential applications in quantum communications and quantum information processing. We describe and demonstrate a technique for coupling single nitrogen vacancy (NV) centers to suspended diamond photonic crystal cavities with quality factors up to 6000. Specifically, we present an enhancement of the NV center’s zero-phonon line fluorescence by a factor of 7 in low-temperature measurements.
