The interaction of a single quantum emitter with its environment is a centraltheme in quantum optics. When placed in highly confined optical fields, such asthose created in optical cavities or plasmonic structures, the opticalproperties of the emitter can change drastically. In particular, photoniccrystal (PC) cavities show high quality factors combined with an extremelysmall mode volume. Efficiently coupling a single quantum emitter to a PC cavityis challenging because of the required positioning accuracy. Here, wedemonstrate deterministic coupling of single Nitrogen-Vacancy (NV) centers tohigh-quality gallium phosphide PC cavities, by deterministically positioningtheir 50 nm-sized host nanocrystals into the cavity mode maximum withfew-nanometer accuracy. The coupling results in a 25-fold enhancement of NVcenter emission at the cavity wavelength. With this technique, the NV centerphotoluminescence spectrum can be reshaped allowing for efficient generation ofcoherent photons, providing new opportunities for quantum science.
