“…The first four levels of our five-level scheme use the same ladder schemes described above, while the fifth (|5 ) corresponds to the adjacent Rydberg state. A similar five-level configuration was investigated previously, where interesting atomic spectra that are not accessible with the basic four-level system were observed [15]. In this paper we show that the addition of the adjacent Rydberg resonance tuning (ARRT) RF field allows for EIT/AT detection of continuous frequencies of the SIG field.…”

“…Resonant interactions are much more sensitive than the Stark effect, though they are limited to detection of discrete frequencies. However, Rydberg states can have strong couplings to many nearby states [15]. We show that by coupling multiple Rydberg levels we can effectively extend the frequency range of the resonant interaction, increasing the sensitivity to microwave fields far-detuned from a resonance transition.…”

“…133 Cs, while in Refs. [15,24] 85 Rb is used. For this six-level 133 Cs model we follow a similar process to the one given in [15,24] and we start by noting that the power of the probe beam measured on the detector (the EIT signal, i.e., the probe transmission through the vapor cell) is given by [25]…”

We demonstrate the use of multiple atomic-level Rydberg-atom schemes for continuous frequency detection of radio frequency (RF) fields. Resonant detection of RF fields by electromagneticallyinduced transparency and Autler-Townes (AT) in Rydberg atoms is typically limited to frequencies within the narrow bandwidth of a Rydberg transition. By applying a second field resonant with an adjacent Rydberg transition, far-detuned fields can be detected through a two-photon resonance AT splitting. This two-photon AT splitting method is several orders of magnitude more sensitive than off-resonant detection using the Stark shift. We present the results of various experimental configurations and a theoretical analysis to illustrate the effectiveness of this multiple level scheme. These results show that this approach allows for the detection of frequencies in continuous band between resonances with adjacent Rydberg states.

“…The enhancement of dynamic optical response by RF detuning can be understood by a theoretical simulation based on the optical Bloch equation considering the four energy levels [10,11,13,22,34,36]. Taking the energy level of the intermediate state 5P 3/2 as a reference, the Hamiltonian H can be expressed as a matrix form…”

A highly excited Rydberg atom via electromagnetically induced transparency with two color cascading lasers has extreme sensitivity to electric fields of microwave ranging from 100 MHz to over 1 THz. It can be used as susceptible atom-based microwave communication antennas where the carrier wave usually works exactly resonant to the transition between a pair of adjacent Rydberg states with large electric dipole moment. A technique of superheterodyne with a strong on-resonant local microwave oscillator is employed to induce considerable Autler-Townes splitting where the antennas has a highest dynamic response to another weak target signal microwave carrier. To further improve the sensitivity of atomic antenna in communication, we detune the carrier microwave frequency off resonance forming an asymmetrically optical splitting and fix the coupling laser frequency at the shoulder of the stronger one, and optimize the local field strength simultaneously. It gives a sensitivity of 12.50(04) nVcm −1 • Hz −1/2 . Its enhancement mechanism of sensitivity is also proved by a theoretical simulation.
