Solid-state microcavities combining ultra-small mode volume, wide-range resonance frequency tuning, as well as lossless coupling to a single mode fibre are integral tools for nanophotonics and quantum networks. We developed an integrated system providing all of these three indispensable properties. It consists of a nanofibre Bragg cavity (NFBC) with the mode volume of under 1 μm(3) and repeatable tuning capability over more than 20 nm at visible wavelengths. In order to demonstrate quantum light-matter interaction, we establish coupling of quantum dots to our tunable NFBC and achieve an emission enhancement by a factor of 2.7.
结合超小模式体积、宽范围共振频率调谐以及与单模光纤无损耦合的固态微腔是纳米光子学和量子网络的重要工具。我们开发了一个集成系统，具备所有这三种不可或缺的特性。它由一个纳米纤维布拉格腔（NFBC）组成，其模式体积小于1立方微米，在可见光波长下具有超过20纳米的可重复调谐能力。为了演示量子光与物质的相互作用，我们将量子点与我们的可调谐NFBC进行耦合，并实现了2.7倍的发射增强。
