论文摘要
我们提供了一项完整的制造研究，该研究是针对与原子的有效耦合的微孔光学电路（QED）量身定制的。微林结构在透明膜上制造，该透明膜中具有较高的空中纤维边缘耦合效率。此外，Bus Waveguide Pulley Coupler在两个Cesium D线频率下实现了与微孔的关键耦合，而在剖宫产的“魔法”波长处达到了高耦合效率，以创建在微林上方的两个颜色的Evanescent Field Traps的晶格。提出的平台有望实现强大的原子 - 纳米光子杂种量子设备。
We present a complete fabrication study of an efficiently-coupled microring optical circuit tailored for cavity quantum electrodynamics (QED) with trapped atoms. The microring structures are fabricated on a transparent membrane with high in-vacuum fiber edge-coupling efficiency in a broad frequency band. In addition, a bus waveguide pulley coupler realizes critical coupling to the microrings at both of the cesium D-line frequencies, while high coupling efficiency is achieved at the cesium 'magic' wavelengths for creating a lattice of two-color evanescent field traps above a microring. The presented platform holds promises for realizing a robust atom-nanophotonics hybrid quantum device.
