Scanning probe techniques in quantum plasmonics — •Andreas W. Schell, Philip Engel, Günter Kewes, and Oliver Benson — Humboldt-Universität zu Berlin, AG Nanooptik

In recent years, scanning probe technologies like atomic force microscopy have developed into a versatile tool for nano-manipulation and nano-assembly tasks [1]. Using nano-manipulation approaches it has become possible to realize different configurations of the same constituents. Here, we will show the controlled coupling of a single photon emitting nitrogen vacancy (NV) center in nanodiamond to different plasmonic structures as well as its use as a probe for the local density of optical states (LDOS) at the nanoscale [2]. With the NV center glued to the tip of an atomic force microscope the LDOS is mapped out in a very controlled way in all three dimensions, giving insight into the local behavior of the emitter-plasmon coupling.
