摘要:

我们提出了第一个实验实现的相干布拉格散射的一维(1D)系统-两串原子强烈耦合到一个单一的光子模式-通过捕获原子在渐缩光纤(TOF)的倏逝场,这也引导探测光实现。我们报告了来自仅包含约1000个铯原子的弦的近12%的功率反射,与来自随机定位的原子的反射相比增强了两个数量级。这一结果为一维原子-光子系统的集体强耦合铺平了道路。我们的方法还允许几个遥远的一维原子晶体之间的直接纤维连接。

英文摘要:

We present the first experimental realization of coherent Bragg scattering off a one-dimensional (1D) system -- two strings of atoms strongly coupled to a single photonic mode -- realized by trapping atoms in the evanescent field of a tapered optical fiber (TOF), which also guides the probe light. We report nearly 12% power reflection from strings containing only about one thousand cesium atoms, an enhancement of two orders of magnitude compared to reflection from randomly positioned atoms. This result paves the road towards collective strong coupling in 1D atom-photon systems. Our approach also allows for a straightforward fiber connection between several distant 1D atomic crystals.
