Brillouin scattering in multi-core optical fibers for sensing applications

We measure the Brillouin gain spectra in two cores (the central core and one of the outer cores) of a ~3-m-long, silica-based, 7-core multi-core fiber (MCF) with incident light of 1.55 μm wavelength, and investigate the Brillouin frequency shift (BFS) and its dependence on strain and temperature. The BFSs of both the cores are ~10.92 GHz, and the strain- and temperature-dependence coefficients ...

Stimulated Brillouin scattering slow light in optical fibers [Invited]

Stimulated Brillouin scattering (SBS) has become a favorable underlying mechanism in many demonstrations of all-optical variable delay in standard fibers, often referred to as slow and fast light. Over 100 journal papers and numerous conference sessions have been dedicated to SBS slow light since 2005. In this paper, recent research in this area is reviewed. Following a short introduction to th...

Observation of Brillouin gain spectrum in optical fibers in telecommunication band: Effect of pump wavelength

We study the optical wavelength dependence of the Brillouin gain spectrum for a silica single-mode fiber in the range from 1511 to 1555 nm using a measurement setup containing an erbium-doped fiber amplifier (EDFA) in the Brillouin pump path. The Brillouin peak power and linewidth are clearly dependent on the pump wavelength, the trends of which correspond well with the wavelength dependence of...

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...
