最近的进展，在相干控制的单量子光，光子，是一个主题的主要利益，并讨论的旗帜下的量子光子学。在过去的十年中，锥形光纤的亚波长直径腰部（称为光学腰部）在量子光学领域开辟了有希望的新途径，为量子光子学应用的多功能平台铺平了道路。该技术的主要特点是，光场可以在横向方向上被严格限制，同时作为导模长距离传播，并在倏逝区与周围介质发生强相互作用。这一特性带来了令人惊讶的操纵单原子和光纤引导光子的可能性，例如，将来自单原子和固态量子发射器的发射有效地引导到光纤引导模式中，在光纤周围具有几个原子的高光学深度，在光纤周围捕获原子，以及用于光纤引导光子的原子存储器。此外，实现适度的纵向限制在双光子腔中已经能够实现腔量子电动力学的强耦合机制，并且由双光子介导的量子发射极之间的长程偶极-偶极相互作用为具有原子系综的量子非线性光学提供了平台。此外，引导场的纵向分量的存在导致了纳米纤维上手性光物质相互作用的独特能力。在这篇文章中，我们回顾了在全光纤接口上实现量子光子学愿景的MEMS技术的关键发展。
Recent advances in the coherent control of single quanta of light, photons, is a topic of prime interest, and is discussed under the banner of quantum photonics. In the last decade, the subwavelength diameter waist of a tapered optical fiber, referred to as an optical nanofiber, has opened promising new avenues in the field of quantum optics, paving the way toward a versatile platform for quantum photonics applications. The key feature of the technique is that the optical field can be tightly confined in the transverse direction while propagating over long distances as a guided mode and enabling strong interaction with the surrounding medium in the evanescent region. This feature has led to surprising possibilities to manipulate single atoms and fiber-guided photons, e.g. the efficient channeling of emission from single atoms and solid-state quantum emitters into the fiber-guided modes, high optical depth with a few atoms around the nanofiber, trapping atoms around a nanofiber, and atomic memories for fiber-guided photons. Furthermore, implementing a moderate longitudinal confinement in nanofiber cavities has enabled the strong coupling regime of cavity quantum electrodynamics to be reached, and the long-range dipole–dipole interaction between quantum emitters mediated by the nanofiber offers a platform for quantum nonlinear optics with an ensemble of atoms. In addition, the presence of a longitudinal component of the guided field has led to unique capabilities for chiral light–matter interactions on nanofibers. In this article, we review the key developments of the nanofiber technology toward a vision for quantum photonics on an all-fiber interface.
