Spin-dependent optical transitions are attractive for a plethora of applications in quantum technologies. Here we report on utilization of high quality ring resonators fabricated from TiO to enhance the emission from negatively charged boron vacancies (V) in hexagonal Boron Nitride. We show that the emission from these defects can efficiently couple into the whispering gallery modes of the ring resonators. Optically coupled V showed photoluminescence contrast in optically detected magnetic resonance signals from the hybrid coupled devices. Our results demonstrate a practical method for integration of spin defects in 2D materials with dielectric resonators which is a promising platform for quantum technologies.
自旋相关的光学跃迁在量子技术的众多应用中颇具吸引力。在此，我们报告利用由TiO制成的高质量环形谐振器来增强六方氮化硼中带负电荷的硼空位（V）的发射。我们表明，这些缺陷的发射可以有效地耦合到环形谐振器的回音壁模式中。光学耦合的V在来自混合耦合器件的光学检测磁共振信号中显示出光致发光对比度。我们的结果展示了一种将二维材料中的自旋缺陷与介电谐振器集成的实用方法，这是量子技术的一个有前景的平台。
