Nanophotonics in Diamond

Abstract

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. This thesis presents some recent contributions to the field of diamond nanophotonics: Increase in single photon collection from 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 such as ring resonators and photonic crystal cavities. In addition, the generation of high quality integrated diamond devices allows for the exploration of nonlinear processes in diamond. Here, we show for the first time optical parametric oscillations in diamond resonators.
