TLDR
In this paper, a technique for the distortion reduction of delayed pulses in single and cascaded slow light delay lines is demonstrated, based on the overlap of different independent Brillouin gains.Abstract:
A technique for the distortion reduction of delayed pulses in single and cascaded slow light delay lines is demonstrated. The method is based on the overlap of different independent Brillouin gains. With three Brillouin lines a distortion reduction of around 30% in a two-segment delay line was achieved.read more

Slow and Fast Light
TL;DR: In this paper, it is shown that the group velocity gives the velocity with which a pulse of light propagates through a material system, depending on the value of group velocity vg in comparison to the velocity of light in vacuum.
Fundamentals and Applications of Slow Light
TL;DR: In this paper, the authors presented a method with experimental demonstrations for improving the maximum fractional delay of a slow-light medium using a multiple-gain-line medium and showed that the spectral sensitivity of slow light media is proportional to the group index of the medium inside the slow light medium.

Gigahertz-Wide Optically Reconfigurable Filters Using Stimulated Brillouin Scattering
Avi Zadok,Avishay Eyal,Moshe Tur +2 more
TL;DR: In this article, flat-top sharp optical filters of gigahertz bandwidth are realized using stimulated Brillouin scattering (SBS) to convert double sideband to single sideband (SSB) modulations for 1-GHz wide linear-frequency-modulated (LFM) signals of arbitrary radio-frequency carrier.

TL;DR: Both numerical calculations and experiments show that an optimal design of a triple-gain-line medium can achieve a maximal fractional delay about twice that which can be obtained with a single- gain-linemedium, at three times higher modulation bandwidth, while high data fidelity is still maintained.

TL;DR: It is demonstrated that stimulated Brillouin scattering can be used to generate all-optical slow-light pulse delays of greater than a pulse length for pulses as short as 16 ns in a single-mode fiber, and strongly suggest that analogous delays can be achieved using stimulated Raman scattering at telecommunication data rates.

Long optically controlled delays in optical fibers.
TL;DR: Optically controlled delay lines in optical fibers are demonstrated by use of the group-velocity control of signal pulses based on stimulated Brillouin scattering, and a large amount of pulse broadening is observed, which agrees well with a theoretical prediction based on linear theory.

Improving the bandwidth of SBS-based slow-light delay
TL;DR: Frequency modulating the pump laser in SBS slow-light delay systems increases the effective Brillouin bandwidth by nearly two orders of magnitude, making the fiber-brassouin amplifier technique applicable to all-optical controllable delay of Gb/s data.
