Large arrays of uniform, precisely tunable, open-access optical microcavities with mode volumes as small as 2.2 μm(3) are reported. The cavities show clear Hermite-Gauss mode structure and display finesses up to 460, in addition to quality (Q) factors in excess of 10,000. The cavities are attractive for use in quantum optics applications, such as single atom detection and efficient single photon sources, and have potential to be extended for experiments in the strong coupling regime.
研究人员报道了一种具有大规模、均匀、精确可调、开放接入的光学微腔阵列，其模式体积小至 2.2μm(3)。这些微腔具有清晰的厄米-高斯模式结构，并且除了具有超过 10000 的品质因数（Q）之外，还具有高达 460 的精细度。这些微腔非常适合用于量子光学应用，例如单原子探测和高效单光子源，并且有潜力扩展到强耦合状态下的实验中。
