通过设计由近1000个嵌入微谐振器中的原子段组成的原子几何结构，我们观察到原子晶格在通信波长处引起的布拉格共振。铒原子在氮化硅（SiN）微谐振器内的晶格中的几何排列减少了与晶格相称的波长处的散射损耗。我们确认依赖的光发射的原子位置和晶格间距，也观察到Fano干涉系统中的共振模式之间。
By engineering atomic geometries composed of nearly 1000 atomic segments embedded in micro-resonators, we observe Bragg resonances induced by the atomic lattice at the telecommunication wavelength. The geometrical arrangement of erbium atoms into a lattice inside a silicon nitride (SiN) microring resonator reduces the scattering loss at a wavelength commensurate with the lattice. We confirm dependency of light emission to the atomic positions and lattice spacing and also observe Fano interference between resonant modes in the system.
