High-Q plasmonic resonances from a transfer-printed diamond ring on a silver surface

Type: article
Abstract: Optically addressable point defects in diamond are promising physical platforms in quantum technologies. In particular, defects embedded in plasmonic devices can interact strongly with photons and provide a robust approach to engineering spin-photon interfaces. However, diamond-based plasmonic devices have low quality factors of Q ≲ 1 0 , constrained by fabrication difficulties. This study demonstrates the high- Q plasmonic resonance of optical emissions from nitrogen-vacancy centers in diamond ring structures onto a silver surface, and experimentally shows that Q ≈ 179 . The proposed device can be easily fabricated using the transfer printing technique. These results address the lack of high- Q plasmonic cavities in diamond-based technologies.
