Fig. 6: Sensitivity of the atomic receiver based on structural enhancement technology.
From: Self-dressing Rydberg atomic receiver based on laser-induced DC field
The operating frequency of the resonant enhancement structure is adjusted using a tunable capacitor, and it is placed in a shielding box for sensitivity testing. During the test, the laser beam position and laser power are consistent with those set in Fig. 4. In the figure, the orange dashed line and green dashed line fit the variation trends of the first-order linear intervals at 20 kHz and 100 kHz, respectively.
