论文摘要
基于Rydberg EIT的微波传感，由于光学泵送速率的基本限制至其深色状态，因此微波转换带宽有限。我们证明了通过两光子激发和两个微波磁场的光学探针和耦合场的参数六波混合，驱动了$δ$的频率偏移，驱动了rydberg-rydberg the themal Atomic vapor中的$δ$。在本实验中实现了微波转换带宽$ 17 $ MHz的带宽，该实验受到可用耦合能力的限制。对系统的进一步理论研究呈现较高的调制带宽，并具有较大的耦合rabi频率。
Rydberg EIT-based microwave sensing has limited microwave-to-optical conversion bandwidth due to fundamental limitation in the optical pumping rate to its dark state. We demonstrate a parametric six-wave mixing of optical probe and coupling fields driving the atoms to a Rydberg state via two-photon excitation and two microwave fields with frequency offset of $δ$ driving the Rydberg-Rydberg transition in thermal atomic vapor. Microwave-to-optical conversion bandwidth of $17$ MHz is achieved in the present experiment which is limited by the available coupling power. Further theoretical investigation of the system presents higher modulation bandwidth with larger coupling Rabi frequency.
