Ultra-compact metallic interface for NV spin readout (Conference Presentation)

Paper Abstract

The spin-optical properties of nitrogen-vacancy (NV) centers in diamond have been demonstrated to enable a plethora of applications ranging from nanoscale sensing to quantum information technologies. The conventional design of NV-based devices requires separate infrastructures for delivering microwave (MW) excitation and guiding/collecting fluorescence signals. Typically, one fabricates dielectric waveguides or lenses next to metallic MW antennae. Here we showed that the device compactness can be substantially improved by the integration of NV centers with channel plasmonic waveguides milled in an optically thick metal layer that simultaneously acts as a MW antenna. The use of highly conductive plasmonic materials allows to fabricate monolithic ultra-compact structures supporting propagation of both MW and optical signals. We demonstrated optical readout of spin resonance by collecting channel plasmon polaritons scattered from the waveguide end.
