光学微腔允许我们将光强烈地限制在小模体积和长光子寿命中。这种约束显著增强了腔内光与物质之间的相互作用，应用于纳米粒子的光捕获和冷却、单光子发射增强、量子信息处理和传感等领域。对于许多应用，直接访问模式体积的开放谐振器是必要的。在这里，我们报告了一个可扩展的，开放访问的光学微腔平台，其模式体积< 30 lambda(3)，精细度接近5 x 10(5)。这一结果明显超过了迄今为止法布里-珀罗微腔的最高光学增强因子。该平台为依赖强光-物质相互作用的高性能量子器件提供了构建块。(c) 2021作者。除另有说明外，所有文章内容均遵循知识共享署名（CC BY）许可协议（http://creativecommons.org/licenses/by/4.0/）。
Optical microcavities allow us to strongly confine light in small mode volumes and with long photon lifetimes. This confinement significantly enhances the interaction between light and matter inside the cavity with applications such as optical trapping and cooling of nanoparticles, single-photon emission enhancement, quantum information processing, and sensing. For many applications, open resonators with direct access to the mode volume are necessary. Here, we report on a scalable, open-access optical microcavity platform with mode volumes < 30 lambda(3) and finesse approaching 5 x 10(5). This result significantly exceeds the highest optical enhancement factors achieved to date for Fabry-Perot microcavities. This platform provides a building block for high-performance quantum devices relying on strong light-matter interactions. (c) 2021 Author(s).
