A comprehensive study of three-photon electromagnetically-induced transparency (EIT) and absorption (EIA) on the rubidium cascade 5S 1/2 → 5P 3/2 (laser wavelength 780 nm), 5P 3/2 → 5D 5/2 (776 nm), and 5D 5/2 → 28F 7/2 (1260 nm) is performed. The 780-nm probe and 776-nm dressing beams are counter-aligned through a Rb room-temperature vapor cell, and the 1260-nm coupler beam is co-or counter-aligned with the probe beam. Several cases of EIT and EIA, measured over a range of detunings of the 776-nm beam, are studied. The observed phenomena are modeled by numerically solving the Lindblad equation, and the results are interpreted in terms of the probe-beam absorption behavior of velocity-and detuning-dependent dressed states. To explore the utility of three-photon Rydberg EIA/EIT for microwave electric-field diagnostics, a sub-THz field generated by a signal source and a frequency quadrupler is applied to the Rb cell. The 100.633-GHz field resonantly drives the 28F 7/2 ↔ 29D 5/2 transition and causes Autler-Townes splittings in the Rydberg EIA/EIT spectra, which are measured and employed to characterize the performance of the microwave quadrupler.

“…Therefore, we discuss a measurement scheme using a superheterodyne receiver, where a local oscillator field is introduced to amplify the system response to the weak IF electric field and measure the field. At an electric field frequency of 30 MHz, a minimum field strength of 30 μV/cm is obtained with a sensitivity of up to dBm/Hz and a linear dynamic range of over 65 dB [45].…”

Microwave sensing offers important applications in areas such as data communication and remote sensing. It has thus received much attention from academia, industry, and governments. Atomic wireless sensing uses the strong response of the large electric dipole moment of a Rydberg atom in response to an external field to achieve precise measurement of a radio frequency (RF) signal. This method offers advantages over traditional wireless sensing including ultrawide energy level transitions, which makes it responsive to RF electric fields over a wide bandwidth. Here, we briefly review the progress of electric field measurement based on Rydberg atoms. We discuss the properties of Rydberg atoms, measurement using Rydberg atoms, experimental progress in electric field measurement of different bands, and different methods for detecting electric fields (such as atomic superheterodyne, machine learning, and critically enhanced measurement). The development of Rydberg atomic measurement focuses on the advantages of Rydberg atomic sensing, especially when compared to conventional microwave receivers. This work is of major significance to developing Rydberg-based measurements in astronomy, remote sensing, and other fields.

“…Even in room temperature atomic vapours, EIT has allowed the sensitivity of Rydberg atoms to electromagnetic fields to be harnessed in novel types of atom-based sensing [5][6][7][8][9][10][11][12][13] that has in turn promoted the advent of new quantum technologies and devices [14]. Such Rydberg-atom-based sensors have a broad array of applications including ultrabroadband radio-frequency (RF) detection [7,10,15], low- [5,16,17] and high-intensity [18,19] RF field detection beyond the range and capabilities of traditional RF field and power sensors, receivers, antennas, and measurement tools. Hybrid devices combining traditional RF technologies with Rydberg atom-based EIT detection for enhanced capabilities and novel application in RF sensing and metrology have also been realized [20][21][22].…”

We investigate the time dependence of atom-light and atom-RF field interactions in Rydberg electromagnetically-induced transparency (EIT) in a room-temperature and heated vapour cell. Quantum-optical transients are observed with rapid onset and dissolution of EIT induced by coupler-light pulses. The formulation and dissolution times of EIT, transient signals, and their dependencies on light intensities and Rydberg-atom density are studied. Simulations of pulsed EIT are performed by solving a time-dependent three-level master equation, whose results are in excellent agreement with experimental observations, including accurately reproducing quantum-optical transients observed at both onset and dissolution. We explore the time-dependent response of EIT to RF fields resonant with a Rydberg–Rydberg transition. An upper limit to the fundamental atom-RF field response time and instantaneous RF detection bandwidth with EIT-based sensors and receivers is established.
