Plasmonic Bragg Cavity-Enhanced Emission from Single Germanium Vacancy Centers in Nanodiamonds (QW6A.7)

Presenter: S Kumar, University of Southern Denmark (SDU)

We experimentally demonstrate ~24 times enhanced decay-rate of a germanium vacancy (GeV) center in a nanodiamond utilizing a bullseye plasmonic cavity. A grating around the cavity is utilized for efficient outcoupling and collection from the cavity.
