“…Furthermore, by exploiting multi-YIG spheres or multimagnon modes systems, the amplification or absorption bandwidth can be increased, resulting in a broadband coherent signal store device. The sharp peak and asymmetric Fano line shape indicate that our platform has great potential in the application of highprecision measurement of weak microwave fields [74,75]. Our two-tone pump scheme and phase-tunable interference can also be accomplished in other coupled-resonator systems, such as optomechanical resonators, which explores effects of mechanical pump on light transmission [76][77][78][79][80][81][82][83][84], and even in circuit-QED systems, in which photon transmission can be controlled through a circuit-QED system [85][86][87][88].…”

We study the phase-controlled transmission properties in a compound system consisting of a threedimensional copper cavity and an yttrium-iron-garnet (YIG) sphere. By tuning the relative phase of the magnon pumping and cavity-probe tones, constructive and destructive interferences occur periodically, which strongly modify both the cavity-field transmission spectra and the group delay of light. Moreover, the tunable amplitude ratio between pump-probe tones allows us to further improve the signal absorption or amplification, accompanied by either significantly enhanced optical advance or delay. Both the phase and amplitude ratio can be used to realize in situ tunable and switchable fast-slow light. The tunable phase and amplitude ratio lead to the zero reflection of the transmitted light and an abrupt fast-slow light transition. Our results confirm that direct magnon pumping through the coupling loops provides a versatile route to achieve controllable signal transmission, storage, and communication, which can be further expanded to the quantum regime, realizing coherent-state processing or quantum-limited precise measurements.

A multi-band atomic candle with microwave-dressed Rydberg atoms

et al. 2022

View full text Add to dashboard Cite

Stabilizing important physical quantities to atom-based standards lies at the heart of modern atomic, molecular and optical physics, and is widely applied to the field of precision metrology. Of particular importance is the atombased microwave field amplitude stabilizer, the so-called atomic candle. Previous atomic candles are realized with atoms in their ground state, and hence suffer from the lack of frequency band tunability and small stabilization bandwidth, severely limiting their development and potential applications. To tackle these limitations, we employ microwave-dressed Rydberg atoms to realize a novel atomic candle that features multi-band frequency tunability and large stabilization bandwidth. We demonstrate amplitude stabilization of microwave field from C-band to Kaband, which could be extended to quasi-DC and terahertz fields by exploring abundant Rydberg levels. Our atomic candle achieves stabilization bandwidth of 100 Hz, outperforming previous ones by more than two orders of magnitude. Our simulation indicates the stabilization bandwidth can be further increased up to 100 kHz. Our work paves a route to develop novel electric field control and applications with a noise-resilient, miniaturized, sensitive and broadband atomic candle.
