我们报道了一种新型的单光子源，它使用一个钙离子捕获在两根光纤的端面之间。光纤充当光子通道，此外，它们的金属外壳为离子提供了一个捕获电场。我们的系统成功地将稳定的单原子发射器与光纤相结合，展示了卓越的紧凑性和可扩展性。因此，它非常适合在量子网络中使用，在量子网络中，单离子与单光子通过光纤传播。我们已经证明了这种有效光源在连续和脉冲模式下产生的光子的非经典特性。
We report on a novel single-photon source using a single calcium ion trapped between the end facets of two optical fibers. The optical fibers act as photonic channels, and in addition their metallic jackets provide a trapping electric field for the ion. Our system successfully combines a stable single-atom emitter with fiber optics, demonstrating remarkable compactness and scalability. In consequence, it is very well suited for use in quantum networks, where single ions interface with single photons traveling through optical fibers. We have demonstrated the non-classical character of the photons generated by this efficient source in continuous as well as pulsed mode.
