Analog time-reversal of optically-carried RF signals with a rare earth ion-doped processor with broadband potential
2018
We propose a novel analog architecture for timereversing optically carried RF signals, based on a rare-earth atomic processor. Our scheme combines long processed signals duration (> 10 μs), potentially GHz bandwidth, direct access to the signal field amplitude, and compatibility with phase-modulated signals. The combination of these features makes this architecture ideal for refocusing RF signals distorted by their propagation in a reverberating environment.
