论文摘要
我们展示了与冷冻兼容的，完全纤维整合的无对准光学微孔子。与低温的兼容性将其可能的应用扩展到了固态量子光学元件的广泛场，在这种量子的情况下通常是必需的。在4.6 K的温度下，我们获得$ \ Mathbf {（9.9 \ pm 0.7）\ times 10^6} $的质量因子。结合纳米纤维提供的较小模式的体积，该空腔可以在相干动力学或快速腔体状态中使用，在该状态下，它可以提供高达15的purcell因子。因此，我们的谐振器适合于显着增强光线和各种不同的量子发射器之间的耦合，并且由于其在范围内的范围而实现了量的量，并且还可以实现量范围。
We demonstrate a cryo-compatible, fully fiber-integrated, alignment-free optical microresonator. The compatibility with low temperatures expands its possible applications to the wide field of solid-state quantum optics, where a cryogenic environment is often a requirement. At a temperature of 4.6 K we obtain a quality factor of $\mathbf{(9.9 \pm 0.7) \times 10^6}$. In conjunction with the small mode volume provided by the nanofiber, this cavity can be either used in the coherent dynamics or the fast cavity regime, where it can provide a Purcell factor of up to 15. Our resonator is therefore suitable for significantly enhancing the coupling between light and a large variety of different quantum emitters and due to its proven performance over a wide temperature range, also lends itself for the implementation of quantum hybrid systems.
