As a solid state platform with unique properties and a variety of color centers that can be optically addressed, diamond has great potential for the realization of integrated photonic networks. However, initial studies of color centers were bound to bulk diamond crystals and nanocrystals due to the difficulties associated in generating diamond devices. Recently, it has become possible to create high performance optical elements based on single crystal diamond that single photon sources can couple to. Hausmann, Choy et al. (pp. 1619–1630) present recent advances in the field of diamond nanophotonics based on nitrogen-vacancy centers as single photon source. These include the efficient extraction of single photons in a nanowire geometry, enhancement of the spontaneous emission rate in metallic resonators, and on-chip single photon routing using integrated optical devices. This development towards controlled integration of color centers in nanodevices will lead towards realization of scalable quantum photonic networks.
