Abstract

Rydberg atom-based superheterodyne with additional local oscillator (LO) signal is a novel approach to detect electric field with high measured sensitivity. However, the LO signal is often supplied to the atomic vapor cell by free-space illumination, which lacks mobility and integration for practical applications. Here, we present a LO port integrated split-ring resonator for realizing high sensitivity-enhanced electric field measurements. The LO signal is sent directly to the resonator through a parallel-plate waveguide, which is shown to achieve a sensitivity enhancement of 32 dB. The integrated resonator has an electrical size of 0.088λ and the feed port S11 reaches −38.2 dB.

用于增强基于雷德贝格原子的电场测量的局域振荡器端口集成谐振器

基于雷德堡原子的超外差分仪带有额外的本地振荡器（LO）信号，是一种具有高测量灵敏度的电场探测新方法。然而，LO 信号通常是通过自由空间照明提供给原子蒸发池的，在实际应用中缺乏移动性和集成性。在此，我们提出了一种用于实现高灵敏度增强型电场测量的 LO 端口集成分环谐振器。LO 信号通过平行板波导直接发送到谐振器，其灵敏度提高了 32 dB。集成谐振器的电气尺寸为 0.088λ，馈电端口 S11 达到 -38.2 dB。
