Diamond nanophotonics and applications in quantum science and technology

Diamond nanophotonics have evolved tremendously from the study of color centers in bulk single crystals and nanocrystals to their characterization in nanostructured environments. This development was facilitated by the ability to generate monolithic, sophisticated nanodevices in high quality single crystal diamond. Here, we present some recent contributions to the field of diamond nanophotonics: increase in single photon collection from nitrogen vacancy (NV) centers embedded in diamond nanowires, broadband spontaneous emission enhancement of single NV centers in plasmonic resonators, and coupling of single NV centers to planar resonators on‐chip.
