The negatively charged nitrogen-vacancy (NV−) center in diamond has been studied in recent years on account of possible applications in quantum information processing, spin-electronics and, e.g., biophotonics. Particular focus has been drawn onto its optical properties. We report on polarization-dependent optical studies of NV− centers in diamond subjected to high magnetic fields of up to 10 T. We observe asymmetric Zeeman splitting of the zero-phonon line photoluminescence, a strong optical alignment as well as Faraday rotation at room temperature. The linear polarization properties of the NV− photoluminescence are studied as function of the diamond crystal orientation in the stationary and time-resolved regimes.
