论文摘要
HF和VHF（3 MHz至300 MHz）频段中的无线电频率对于基于Rydberg Atom的检测方案来说是具有挑战性的，因为共振检测需要激发原子到极高的能量状态。我们演示了一种通过受控的自动镇分裂来检测和测量HF和VHF频段中射频（RF）载体的方法。使用共振，高频（GHz）RF场，可以增强由低频创建的Townes-Merrit侧带的吸收信号，可以增强非谐波RF场。值得注意的是，该技术使用了避免过境的光学频率分离的测量，以确定非共振，低频RF场的幅度。该技术还提供了低频RF电场的频率选择测量。为了证明这一点，我们证明了在低频VHF载体上的振幅调制信号转导。我们进一步证明了同时接受多种音调的接收，从而在VHF范围内创建了Rydberg的“ Spectrum Analyzer”。
Radio frequencies in the HF and VHF (3 MHz to 300 MHz) bands are challenging for Rydberg atom-based detection schemes, as resonant detection requires exciting the atoms to extremely high energy states. We demonstrate a method for detecting and measuring radio frequency (RF) carriers in the HF and VHF bands via a controlled Autler-Townes line splitting. Using a resonant, high-frequency (GHz) RF field, the absorption signal from Townes-Merrit sidebands created by a low frequency, non-resonant RF field can be enhanced. Notably, this technique uses a measurement of the optical frequency separation of an avoided crossing to determine the amplitude of a non-resonant, low frequency RF field. This technique also provides frequency-selective measurements of low frequency RF electric fields. To show this, we demonstrate amplitude modulated signal transduction on a low frequency VHF carrier. We further demonstrate reception of multiple tones simultaneously, creating a Rydberg `spectrum analyzer' over the VHF range.
