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…

Slow light between two absorbing resonance in asymmetry double quantum dots

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

Broadband optical delay with a large dynamic range using atomic dispersion

We report on a tunable all-optical delay line for pulses with optical frequency within the Rb D2 absorption line. Using frequency tuning between absorption components from different isotopes, pulses

Simple technique to achieve fast light in gain regime using Brillouin scattering.

TLDR
A novel technique based on stimulated Brillouin scattering for propagating fast light (signal advancement) with low distortion in optical fibers by introducing a modulation of the current driving the pump laser to achieve a delay-bandwidth product close to the optimum conditions.

Implementations of slow light using double-resonances

Many practical applications of slow optical pulse propagation (slow light) require that a pulse be delayed by many times its temporal width, or equivalently that the product of the pulse’s delay and

Reducing group-velocity-dispersion-dependent broadening of stimulated Brillouin scattering slow light in an optical fiber by use of a single pump laser

We propose a method of effectively extending the stimulated Brillouin scattering (SBS) gain bandwidth in a single-mode optical fiber to reduce group-velocity-dispersion (GVD)-dependent pulse spread

TLDR
An experimental study on ultraslow propagation of matched optical pulses in nondegenerate four wave mixing (FWM) in hot potassium vapor finds fractional delay and fractional broadening to be 1.1 and 1.2.

In this Rapid Communication we report an experimental observation of temporal delay control of large-spectral-bandwidth multimode laser pulses by means of electromagnetically induced transparency. We

Physical limits to broadening compensation in a linear slow light system.

TLDR
This work obtains some physical limits to broadening compensation in linear slow light systems based on simple Fourier analysis and shows that gain and dispersion broadening can never compensate in such a system.

Improving coherent atomic vapor optical buffers

We report on a theoretical study of the influence of incoherent optical pumping and beam profiling on slow light propagation in three-level atomic vapor. The pumping reduces the residual unwanted

TLDR
It is found that partial overlap of the Stokes and anti-Stokes resonances can actually lead to an enhancement of the slow-light delay-bandwidth product when Deltaomegapsime1.3OmegaB.
