Abstract
Section titled āAbstractāWe report on detecting continuous 60-GHz microwave radiation with powers in the nanowatt range by the photoluminescence of an ensemble of negatively charged nitrogen vacancy (NVā) centers in diamond at room temperature. The high contrast of the optically detected magnetic resonance and the efficient photon collection yield a magnetic field sensitivity of 86 nT/Hz for continuous-wave laser excitation with a photon energy of 2.33 eV and a power density of 93 W/cm2. The efficiency of the microwave-power-to-magnetic-field conversion amounts to 0.54 mT/W. The microwave excitation also enhances the degree of the linear polarization of NVā photoluminescence at magnetic resonance conditions, and for linearly co-polarized NVā photoluminescence and laser light, the magnetic field sensitivity is improved by about 7%.
