论文摘要
提出了一个集成的光子平台，用于原子束与无退火高质量因子（Q）微孔子之间的强烈相互作用。我们在$ 〜780 $ nm的光学转换周围制造了一个薄膜，浅色的罪恶微孔子索人，其Q {87} $ rb的光学过渡周围的Q {87} $ rb的光学过渡周围。该Q是可以实现的，而无需在高温下退火，从而使未来的完全集成的平台也可以包含光电电路。估计的单光子RABI频率（2G）为$ {2 \boldsymbolπ} \ times $ 64 MHz，在谐振器上方100 nm的高度上。我们的仿真结果表明，纵向速度为0.2 m/s至30 m/s的微型原子梁将与我们的谐振器强烈相互作用，从而可以检测到单原子转移并实现可扩展的单原子光子设备。具有类似Q的赛车谐振器可用于检测速度约为300 m/s的热原子束。
An integrated photonic platform is proposed for strong interactions between atomic beams and annealing-free high-quality-factor (Q) microresonators. We fabricated a thin-film, air-clad SiN microresonator with a loaded Q of $1.55\times10^6$ around the optical transition of $^{87}$Rb at $~780$ nm. This Q is achieved without annealing the devices at high temperatures, enabling future fully integrated platforms containing optoelectronic circuitry as well. The estimated single-photon Rabi frequency (2g) is ${2\boldsymbolπ}\times$64 MHz at a height of 100 nm above the resonator. Our simulation result indicates that miniature atomic beams with a longitudinal speed of 0.2 m/s to 30 m/s will strongly interact with our resonator, allowing for the detection of single-atom transits and the realization of scalable single-atom photonic devices. Racetrack resonators with a similar Q can be used to detect thermal atomic beams with velocities around 300 m/s.
