Slow light with large fractional delays by spectral hole-burning in rubidium vapor

Ryan M. Camacho, Michael Vern Pack, John C. Howell

We report on the experimental realization of large fractional pulse delays in a hot, Doppler-broadened rubidium vapor. A pump laser burns a deep spectral hole in the inhomogeneously broadened vapor. The delay is shown to be widely tunable by both power broadening the resonance and frequency modulating the pump laser. The simplicity of the scheme opens up the possibility for practical optical delays and buffers.

Controllable ultrabroadband slow light in a warm rubidium vapor

Rui Zhang, Joel A. Greenberg, Martin C. Fischer +1 more

We study ultrabroadband slow light in a warm rubidium vapor cell. By working between the D1 and D2 transitions, we find a several-nanometer window centered at 788.4 nm in which the group index is highly uniform and the absorption is small (<1%). We demonstrate that we can control the group delay by varying the temperature of the cell, and we observe a tunable fractional delay of 18 for pulses as short as 250 fs (6.9 nm bandwidth) with a fractional broadening of only 0.65 and a power leakage of 55%. We find that a simple theoretical model is in excellent agreement with the experimental results. Using this model, we discuss the impact of the pulse’s spectral characteristics on the distortion it incurs during propagation through the vapor.We study ultrabroadband slow light in a warm rubidium vapor cell.

Large group delays and long storage times for optical pulses in atomic vapor cells

Irina V. Novikova, D. F. Phillips, Ronald Lee Walsworth

We achieve large fractional delays in slow and stored light in atomic vapors using temporally shaped control fields. Combined with amplification, temporal control allows for pulse transmission with pulse bandwidth preservation and minimal distortion.
