We experimentally demonstrate a novel technique to realize a tunable delay line based on dynamic Brillouin gratings in a high birefringence fiber. A 8 ns pulse signal is continuously delayed up to 184 ns with minor distortion.
Review on recent progress in the slow and fast light based on Brillouin scattering in optical fibers will be presented, where the brief history, the experimental results, and current research trends will be included.
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 fibre. This control is achieved by means of the gain and loss mechanisms of stimulated Brillouin scattering in the fibre itself. Our experiments show that group velocities below 71,000 km/s on one hand, well exceeding the speed of light in vacuum on...
Broadband slow light is demonstrated using stimulated Brillouin scattering in optical fibers based on double Brillouin pump. A 25-GHz bandwidth is achieved, resulting in a variable time delay up to 10.9 ps with 37-ps pulses.
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 other hand and even negative group velocities can readily be obtained
We experimentally demonstrate 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
