A Multi-Band Rydberg-Atom Based Receiver/Antenna: AM/FM Stereo Reception
Christopher L. Holloway, Matthew T. Simons, Joshua A. Gordon
With the re-definition of the International System of Units (SI) that occurred in October of 2018, there has recently been a great deal of attention in the development atom-base sensors for metrology applications. In particular great progress had been made in using Rydberg-atom based techniques for electric (E) field metrology. These Rydberg-atom based E-field sensors have made it possible to develop atom-based receiver and antennas, which potentially have many benefits over conventional technologies in the detection and receiving modulated signals. In this paper, we demonstrate the ``first'' multi-channel atom-based reception of both amplitude (AM) and frequency (FM) modulation signals. We demonstrate this by using two different atomic species in order to detect and receive AM and FM modulated signals in stereo. Also, in this paper we investigate the effect of Gaussian noise on the ability to received AM/FM signals. These results illustrated the multi-band (or multi-channel) receiving capability of a atom- based receiver/antenna to produce high fidelity stereo reception from both a AM and FM modulated signals.
