论文摘要
通过引导和聚焦激光器到芯片上方〜10UM以捕获，状态操纵和读数单个rubidium原子，提出了一个片上的多分散装置，以将激光引导并集中到该区域，从而将片段的多分散装置用于接口单原子和集成的光子电路。对于光学偶极子陷阱，将两个850 nm激光束进行衍射并重叠以形成单原子偶极陷阱的晶格，而光学偶极子的直径在2.7UM上。类似的光栅旨在指导780 nm探针激光激发并收集87RB原子的荧光。这种设备为将来的单个原子的应用提供了紧凑的解决方案，包括单个光子源，单原子量子寄存器和传感器。
An on-chip multi-grating device is proposed to interface single-atoms and integrated photonic circuits, by guiding and focusing lasers to the area with ~10um above the chip for trapping, state manipulation, and readout of single Rubidium atoms. For the optical dipole trap, two 850 nm laser beams are diffracted and overlapped to form a lattice of single-atom dipole trap, with the diameter of optical dipole trap around 2.7um. Similar gratings are designed for guiding 780 nm probe laser to excite and also collect the fluorescence of 87Rb atoms. Such a device provides a compact solution for future applications of single atoms, including the single photon source, single-atom quantum register, and sensor.
