摘要:

利用微加工的法布里-珀罗光学谐振腔实现了原子探测和光子产生,腔模中平均少于1个原子。我们的腔设计结合了微细加工工艺的固有可扩展性和腔场与单模光波导或光纤的直接耦合。原子的存在是通过从腔输入镜反射的探测光的强度和噪声特性的变化来观察的。横向穿过腔的激发激光触发光子发射进入腔模,从而进入单模光纤。这些是在原子芯片上构建光学微腔网络以应用于量子信息处理的第一步。

英文摘要:

A microfabricated Fabry-Perot optical resonator has been used for atom detection and photon production with less than 1 atom on average in the cavity mode. Our cavity design combines the intrinsic scalability of microfabrication processes with direct coupling of the cavity field to single-mode optical waveguides or fibers. The presence of the atom is seen through changes in both the intensity and the noise characteristics of probe light reflected from the cavity input mirror. An excitation laser passing transversely through the cavity triggers photon emission into the cavity mode and hence into the single-mode fiber. These are first steps towards building an optical microcavity network on an atom chip for applications in quantum information processing.
