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.

Recent experiments demonstrating slow light between two absorbing resonances are reviewed as well as some recently demonstrated implementations, including low-light level buffering, image delays and interferometry.

Low-distortion slow light using two absorption resonances

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

We consider group delay and broadening using two strongly absorbing and widely spaced resonances. We derive relations which show that very large pulse bandwidths coupled with large group delays and small broadening can be achieved. Unlike single resonance systems, the dispersive broadening dominates the absorptive broadening which leads to a dramatic increase in the possible group delay. We show that the double resonance systems are excellent candidates for realizing all-optical delay lines. We report on an experiment which achieved up to 50 pulse delays with 40% broadening.We consider group delay and broadening using two strongly absorbing and widely spaced resonances.

Limits on the time delay induced by slow-light propagation

Robert W. Boyd, Daniel J. Gauthier, Alex L. Gaeta +1 more

We show that there are no fundamental limits to the maximum time delay that can be achieved for pulses propagating through slow-light media, thus suggesting the importance of slow-light methods for practical applications.

Slow light between two absorbing resonance in asymmetry double quantum dots

Chunchao Yu, Tao Wang

We demonstrate the slow light in double quantum dots (QDs) resonance dispersion material in theory. The slow factor, absorption, and bandwidth are greatly influenced by the energy difference of the two resonance energy. The bandwidth of this system is up to 60 GHz. The 20 ps input signal pulse is delayed by 180 ps (group index of approximately 55) relative to free-space propagation with little broadening in 1 mm dispersion material for the optical communication wavelength. The signal pulse delay can be tuned by the pump pulse.We demonstrate the slow light in double quantum dots (QDs) resonance dispersion material in theory.
