Multi-contact switch using double-dressing regularity of probe, fluorescence, and six-wave mixing in a Rydberg atom
2018
In this paper, we study the realization of a multi-contact switch using the double-dressing regularity of probe, fluorescence, and six-wave mixing signals in a five-level 85Rb atomic system. For the first time, we compare the dressing regularity of Rydberg states by observing electromagnetically induced transparency and signals. With the scanning probe and dressing fields, both large and small line shifts in signals are observed. The small line shifts are induced by double-dressed line shifts. Also, the big line shifts result from the Rydberg dressing. In addition, with an increase in the principal quantum number n of the Rydberg state, all the signals become weaker, while the line shifts of the signals become enhanced. Using the regularity in line shifts of the signals and an acoustic optical modulator to modulate the frequency detuning, we can realize a multi-contact switch action and fast conversion between different contacts.
