Brillouin slow light: substantial optical delay in the second-order Brillouin gain spectrum.
We experimentally demonstrate optical delay in the second-order Brillouin gain spectrum by incorporating a double Brillouin-frequency shifter into the system. By coinciding the seed signal with the second-order Brillouin gain spectrum, it was found that the seed signal experienced significantly larger delay as compared to the Brillouin slow light generated from the first-order Brillouin spectru...
متن کاملMinimizing distortion and enlarging group delay in Brillouin slow light systems by gain profile optimization
Optimal gain spectra minimizing distortion and enhancing delaying efficiency in linear slow light systems are predicted and experimentally validated by shaping the gain spectral profile in a Brillouin fiber amplifier.

متن کاملDistributed Measurement of Brillouin Gain Spectrum in Photonic Crystal Fibre
Distributed measurements of the Brillouin gain spectrum in a photonic crystal fibre have been carried out for the first time to our knowledge. These measurements confirm the strong increase of the Brillouin threshold as resulting from the broadband and multimode nature of the Brillouin gain spectrum all along the fibre. INTRODUCTION The periodic wavelength-scale air-hole microstructure of solid...
متن کاملRecent advancements in stimulated - Brillouin - scattering slow light
A review on the work performed by our group on slow light via Stimulating Brillouin scattering (SBS) is presented. We describe the fundamentals of the slow-light phenomena and how SBS can be used to obtain tunable optical delays in optical fibers. We then review the mechanisms to overcome the limitations imposed by the narrow SBS resonance bandwidth and to optimize the slow-light performance fo...
متن کاملPolarization-induced distortion in stimulated Brillouin scattering slow-light systems.
The vector analysis of stimulated Brillouin scattering amplification in birefringent fibers is extended to include signal pulses. The analysis finds that the different slow-light delays experienced by the states of polarization corresponding to maximum and minimum gain may result in severe pulse distortion. Thus, a generally polarized pulse, experiencing only a moderate gain, can become broader...
