Absolute magnetometry based on quantum beats in diamond nitrogen-vacancy centers
Kejie Fang, Victor M. Acosta, Charles Santori +5
We demonstrate an absolute magnetometer immune to temperature fluctuation and strain inhomogeneity, based on quantum beats in the ground state of nitrogen-vacancy centers in diamon…
Light narrowing of magnetic resonances in ensembles of nitrogen-vacancy centers in diamond
K. Jensen, V. M. Acosta, A. Jarmola +1
We investigate optically detected magnetic resonance signals from an ensemble of nitrogen-vacancy centers in diamond. The signals are measured for different light powers and microw…
Coupling of Nitrogen-Vacancy Centers to Photonic Crystal Cavities in Monocrystalline Diamond
Andrei Faraon, Charles Santori, Zhihong Huang +2
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…
Room Temperature Operation of a Radiofrequency Diamond Magnetometer near the Shot Noise Limit
Chang S. Shin, Claudia E. Avalos, Mark C. Butler +8
We operate a nitrogen vacancy (NV-) diamond magnetometer at ambient temperatures and study the dependence of its bandwidth on experimental parameters including optical and microwav…
