Bright off-axis directional emission with plasmonic corrugations Hamed Sattari, Alireza R. Rashed, Ekmel Ozbay, and Humeyra Caglayan Author Information
In this work, a new plasmonic bulls-eye structure is introduced to efficiently harvest the emitted light from diamond nitrogen vacancy (NV) centers. We show that the presence of a simple metal
