Highly efficient Brillouin slow and fast light using As2Se3 chalcogenide fiber

摘要

We demonstrate the generation of slow and fast light based on\udstimulated Brillouin scattering in As2Se3 chalcogenide fiber with the best\udefficiency ever reported. The Brillouin gain of 43 dB is achieved with only\ud60-mW pump power in a 5-m single-mode chalcogenide fiber, which leads\udto the optical time delay of 37 ns with a 50-ns Gaussian pulse.
