Chip-integrated plasmonic cavity-enhanced single nitrogen-vacancy center emission [PDF]

, 2017
High temporal stability and spin dynamics of individual nitrogen-vacancy (NV) centers in diamond crystals make them one of the most promising quantum emitters operating at room temperature.

Cavity QED with Diamond Nanocrystals and Silica Microspheres

, 2006
Normal mode splitting is observed in a cavity QED system, in which nitrogen vacancy centers in diamond nanocrystals are coupled to whispering gallery modes in a silica microsphere.

Perfect selective alignment of nitrogen-vacancy centers in diamond [PDF]

Applied Physics Express, 2014
Nitrogen-vacancy (NV) centers in diamond have attracted significant interest because of their excellent spin and optical characteristics for quantum information and metrology. To take advantage of the characteristics, the precise control of the orientation of the N-V axis in the lattice is essential.

Electric-Field-Induced Coherent Control of Nitrogen-Vacancy Centers

Physical Review Applied, 2022
Enabling scalable and energy-efficient control of spin defects in solid-state media is desirable for realizing transformative quantum information technologies. Exploiting voltage-controlled magnetic anisotropy, we report coherent manipulation of nitrogen-vacancy (NV) centers by the spatially confined magnetic stray fields produced by a proximate ...

Terahertz emission from diamond nitrogen-vacancy centers

Science Advances
Coherent light sources emitting in the terahertz range are highly sought after for fundamental research and applications. Terahertz lasers rely on achieving population inversion. We demonstrate the generation of terahertz radiation using nitrogen-vacancy centers in a diamond single crystal.

Two-beam coupling by nitrogen-vacancy centers in diamond [PDF]

Optics Letters, 1992
A new method for two-beam coupling measurements based on acousto-optic modulation with subhertz tuning capability is applied to study excited-state dynamics of the nitrogen-vacancy center in diamond. Results yield fundamental decay constants and the nonlinear refractive index and are in good agreement with the calculated dual grating response to ...

Zero- and Low-Field Sensing with Nitrogen-Vacancy Centers

Physical Review Applied, 2022
Over the years, an enormous effort has been made to establish nitrogen vacancy (NV) centers in diamond as easily accessible and precise magnetic field sensors. However, most of their sensing protocols rely on the application of bias magnetic fields, preventing their usage in zero- or low-field experiments.

Defect evolution in nitrogen-implanted CVD diamond during thermal annealing: The formation of NV centers and vacancy clusters

Materials & Design
We investigate the thermal evolution of implantation-induced defects in single-crystal CVD diamond using depth-resolved positron annihilation lifetime spectroscopy (PALS). Samples were implanted with 0.5MeV N+ ions at a fluence of 1×1014cm−2 and annealed
