  • Controllable ultrabroadband slow light in a warm rubidium vapor
    Zhang, Rui; Greenberg, Joel A.; Fischer, Martin; Gauthier, Daniel J. (Journal of the Optical Society of America B, 2011-11)
    We study ultrabroadband slow light in a warm rubidium vapor cell. By working between the D1 and D2 transitions, we find a several-nanometer window centered at 788:4nm in which the group index is highly uniform and the ...
  • FSBS resonances observed in a standard highly nonlinear fiber
    Wang, Jing; Zhu, Yunhui; Zhang, Rui; Gauthier, Daniel J. (Optics Express, 2011-03-14)
    Forward stimulated Brillouin scattering (FSBS) is observed in a standard 2-km-long highly nonlinear fiber. The frequency of FSBS arising from multiple radially guided acoustic resonances is observed up to gigahertz ...
  • Slow light with a swept-frequency source
    Zhang, Rui; Zhu, Yunhui; Wang, Jing; Gauthier, Daniel J. (Optics Express, 2010-12-10)
    We introduce a new concept for stimulated-Brillouin-scatteringbased slow light in optical fibers that is applicable for broadly-tunable frequency-swept sources. It allows slow light to be achieved, in principle, over the ...
