We numerically demonstrate an optimized circular grating for Nitrogen-Vacancy centers with collection efficiency of 35.8% for Zero-Phonon emission into NA within 0.5, which is improved to 63.9% by adding a conductive layer. The optimal structure is fabricated using transferred hard mask lithography.
