Instruments for distributed fiber-optic measurement of temperature are now available with temperature resolution of 0.01°C and spatial resolution of 1 m with temporal resolution of fractions of a minute along standard fiber-optic cables used for communicat ...
Slow and fast light with null amplification or loss of a light signal is experimentally demonstrated. This novel method for producing zero-gain slow and fast light takes advantage of the great flexibility of stimulated Brillouin scattering in optical fiber ...
Delaying and advancement of optical pulses using stimulated Brillouin scattering in As2Se3 fiber is demonstrated. Pulses can be delayed by 37 ns in a 5-m-long fiber with a pump power as low as 60 mW. ...
Generation of optical delays with minor amplitude change are realized through the superposition of gain and loss profiles generated by stimulated Brillouin scattering. It results in synthesized spectral profiles identical to an ideal electromagnetically-in ...
A method to achieve an extremely wide and flexible control of the group velocity in an optical fiber using stimulated Brillouin scattering is presented. Group velocities below 71,000 km/s on one hand, well exceeding the speed of light in vacuum on the othe ...
We demonstrate a method to achieve an extremely wide and flexible external control of the group velocity of signals as they propagate along an optical fiber. This control is achieved by means of the gain and loss mechanisms of stimulated Brillouin scatteri ...
The Brillouin frequency shift and linewidth were measured over the full temperature range in which the fibre experiences no structural damage, demonstrating that Brillouin sensing can be actually performed from 1 K to 1000 K. ...
We present a new technique for simultaneous measurement of chromatic dispersion and Brillouin shift distribution along conventional, single-mode optical fibers used in telecommunications. It is based on performing Brillouin Optical Time Domain Analysis (BO ...

Stimulated Brillouin scattering makes possible the generation of synthesized gain spectra, so that innovative slow light schemes can be realized, ranging from broadband tunable delays to a zero-gain situation identical to an ideal electromagnetically-induc ...
We demonstrate the generation of slow and fast light based on stimulated Brillouin scattering in As2Se3 chalcogenide fiber with the best efficiency ever reported. The Brillouin gain of 43 dB is achieved with only 60-mW pump power in a 5-m single-mode chalc ...
