Four-fold reduction in the speed of light at practical power levels using Brillouin scattering in a 2-m Bismuth-oxide fiber

摘要

A 2-m long Bismuth-oxide-based highly-nonlinear fiber is used to generate Brillouin-assisted slow-light. Time delays of 46-ns and a four-fold reduction in the speed of light are achieved for 180-ns pulses with a CW pump power of just ～400-mW.
