Quantum Photonic Interface for Tin-Vacancy Centers in Diamond

Germanium-Vacancy Single Color Centers in Diamond

Atomic-sized fluorescent defects in diamond are widely recognized as a promising solid state platform for quantum cryptography and quantum information processing. For these applications, single photon sources with a high intensity and reproducible fabrication methods are required. In this study, we report a novel color center in diamond, composed of a germanium (Ge) and a vacancy (V) and named ...

Hybrid Plasmonic Photonic Crystal Cavity for Enhancing Emission from near-Surface Nitrogen Vacancy Centers in Diamond

Optical cavities create regions of high field intensity, which can be used for selective spectral enhancement of emitters such as the nitrogen vacancy center (NV) in diamond. This report discusses a hybrid metal−diamond photonic crystal cavity, which provides greater localization of the electric field than dielectric cavities and mitigates metalrelated losses in existing plasmonic structures. W...

Coupling of nitrogen-vacancy centers to photonic crystal cavities in monocrystalline diamond.

The zero-phonon transition rate of a nitrogen-vacancy center is enhanced by a factor of ∼70 by coupling to a photonic crystal resonator fabricated in monocrystalline diamond using standard semiconductor fabrication techniques. Photon correlation measurements on the spectrally filtered zero-phonon line show antibunching, a signature that the collected photoluminescence is emitted primarily by a ...
