Diamond-based structures to collect and guide light

Abstract

We examine some promising photonic structures for collecting and guiding light in bulk diamond. The aim of this work is to optimize single photon sources and single spin read-out from diamond color centers, specifically NV? centers. We review the modeling and fabrication (by focused ion beam and reactive ion etching) of solid immersion lenses, waveguides and photonic crystal cavities in monolithic diamond. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.
