论文摘要
已知涉及Rydberg状态的原子系统中电磁诱导的透明度（EIT）是对入射微波（MW）田地的敏感探针，尤其是那些与Rydberg-to-Rydberg Transitions共鸣的探针。在这里，我们提出了Rydberg原子接收器对振幅（AM）和频率调制（FM）信号的响应的可理解分析模型，并将其与实验结果进行比较：我们提出了一个设置，允许使用AM或FM发送信号并评估其效率与降级。此外，该设置揭示了一种新的检测构型，使用所有圆形极化用于光场，并允许检测圆形极化的MW场，并用光学束传播。在我们的测量中，我们系统地介绍了几个参数表现出局部最佳特征，然后估算这些最佳参数和工作范围，从而解决了设计强大的Rydberg MW MW传感器及其操作方案的需求。
Electromagnetically induced transparency (EIT) in atomic systems involving Rydberg states is known to be a sensitive probe of incident microwave (MW) fields, in particular those resonant with Rydberg-to-Rydberg transitions. Here we propose an intelligible analytical model of Rydberg atomic receiver's response to amplitude- (AM) and frequency-modulated (FM) signals, and compare it with experimental results: we present a setup that allows sending signals with either AM or FM and evaluating their efficiency with demodulation. Additionally, the setup reveals a new detection configuration, using all circular polarizations for optical fields and allowing detection of circularly polarized MW field, propagating colinearly with optical beams. In our measurements we systematically present that several parameters exhibit local optimum characteristics and then estimate these optimal parameters and working ranges, addressing the need to devise a robust Rydberg MW sensor and its operational protocol.
