Abstract
We present an experimental study of cavity-Assisted Rydberg-Atom electromagnetically induced transparency (EIT) using a high-finesse optical cavity (F∼28000). Rydberg atoms are excited via a two-photon transition in a ladder-Type EIT configuration. A three-peak structure of the cavity transmission spectrum is observed when Rydberg EIT is generated inside the cavity. The two symmetrically spaced side peaks are caused by bright-state polaritons, while the central peak corresponds to a dark-state polariton. Anticrossing phenomena and the effects of mirror adsorbate electric fields are studied under different experimental conditions. We determine a lower bound on the coherence time for the system of 7.26±0.06μs, most likely limited by laser dephasing. The cavity-Rydberg EIT system can be useful for single-photon generation using the Rydberg blockade effect, studying many-body physics, and generating novel quantum states among many other applications.
