论文摘要
我们研究了与原子蒸气细胞合并的分裂环谐振器（SRR）的使用，以提高基于Rydberg Atom的传感器的灵敏度和最小检测到的电气（E）。在这种方法中，将亚波长SRR放置在一个原子蒸气细胞周围，该原子充满了纤维原子，用于1.3〜GHz的电子场测量。 SRR在增强电子场测量灵敏度方面提供了100倍。 SRR使用电磁诱导的透明度（EIT）（EIT），E-Field测量值降低至5〜mV/m，而在没有SRR的情况下，最小可检测的场为500〜mV/m。我们证明，通过将EIT与基于异差的Rydberg原子混合器方法相结合，SRR允许敏感性为5.5〜 $ $ $ v/m $ \ sqrt {\ rm Hz} $，这是敏感性的两种范围提高的敏感性。
We investigate the use of a split-ring resonator (SRR) incorporated with an atomic-vapor cell to improve the sensitivity and the minimal detectable electric (E) field of Rydberg atom-based sensors. In this approach, a sub-wavelength SRR is placed around an atomic vapor-cell filled with cesium atoms for E-field measurements at 1.3~GHz. The SRR provides a factor of 100 in the enhancement of the E-field measurement sensitivity. Using electromagnetically induced transparency (EIT) with Aulter-Townes splitting, E-field measurements down to 5~mV/m are demonstrated with the SRR, while in the absence of the SRR, the minimal detectable field is 500~mV/m. We demonstrate that by combining EIT with a heterodyne Rydberg atom-based mixer approach, the SRR allows for the a sensitivity of 5.5~$μ$V/m$\sqrt{\rm Hz}$, which is two-orders of magnitude improvement in sensitivity than when the SRR is not used.
