Research paperExperimental CharacterizationComputational MultiscaleReflective Dielectric Cavity Enhanced Emission from Hexagonal Boron Nitride Spin Defect ArraysXiao-Dong Zeng, Yuan-Ze Yang, Nai-Jie Guo, Zhi-Peng Li et al.arXiv·2022·10.48550/arXiv.2207.00714·arXiv:2209.00256AbstractWe demonstrate a reflective dielectric cavity (RDC) to enhance photoluminescence and ODMR contrast of hexagonal boron nitride spin defects. By combining a reflective metal layer, a dielectric spacer, and hBN containing negatively charged boron vacancy (VB-) defects, the experiment achieves about 7-fold PL enhancement and 18% ODMR contrast. Numerical simulations show that the enhancement depends on dielectric thickness and is broadband.Read more
