论文摘要
旋转依赖性光学转变对量子技术中的多种应用具有吸引力。在这里，我们报告了使用TiO2制造的高质量环谐振器的利用，以增强六角形硝化硼的负电荷硼空位的发射。我们表明，这些缺陷的发射可以有效地融入环形谐振器的耳语画廊模式中。光学耦合的硼空位显示了来自混合耦合器件的光学检测到的磁共振信号的光致发光对比。我们的结果证明了一种实用方法，可以将2D材料中的自旋缺陷与介电谐振器整合在一起，这是量子技术的有前途的平台。
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 TiO2 to enhance the emission from negatively charged boron vacancies 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 boron vacancy 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.
