An all-optical tunable pulse delay scheme that utilizes the power-dependent variation of the refractive index that accompanies stimulated Raman scattering in an optical fiber to produce controllable delays in ultra-high bandwidth telecommunication systems.Abstract:
We demonstrate an all-optical tunable pulse delay scheme that utilizes the power-dependent variation of the refractive index that accompanies stimulated Raman scattering in an optical fiber. Using this technique, we delay 430-fs pulses by up to 85% of a pulse width. The ability to accommodate the bandwidth of pulses shorter than 1 ps in a fiber-based system makes this technique potentially viable for producing controllable delays in ultra-high bandwidth telecommunication systems.read more

Arbitrary-bandwidth Brillouin slow light in optical fibers
TL;DR: This paper demonstrates experimentally that Brillouin slow light with an arbitrary large bandwidth can be readily obtained in conventional optical fibers using a simple and inexpensive pump spectral broadening technique and sees no limit to extend this technique to the delaying of GHz-bandwidth signals.

Flatband slow light in photonic crystals featuring spatial pulse compression and terahertz bandwidth
TL;DR: By directly observing the spatial compression of an optical pulse, this work confirms the mechanism underlying this square scaling law and demonstrates slow light with a bandwidth of 2.5 THz and a delay-bandwidth product of 30, which is an order of magnitude larger than any reported so far.

Broadband SBS Slow Light in an Optical Fiber
TL;DR: In this article, the authors investigate slow light via stimulated Brillouin scattering (SBS) in a room temperature optical fiber that is pumped by a spectrally broadened laser and find that partial overlap of the Stokes and anti-Stokes resonances can actually lead to an enhancement of the slow light delay-bandwidth product when Deltaomegapsime 1.3OmegaB.

Observation of pulse delaying and advancement in optical fibers using stimulated Brillouin scattering
TL;DR: This paper demonstrates experimentally that it is possible to control optically the group velocity of an optical pulse as it travels along an optical fiber and derives the basic theory behind these group-delay changes and demonstrates the effect in two kinds of fibers which are conventionally used.
