  • Bunching-induced optical nonlinearity and instability in cold atoms [Invited]
    Greenberg, Joel A.; Schmittberger, Bonnie L.; Gauthier, Daniel J. (Optics Express, 2011-11-07)
    We report a new nonlinear optical process that occurs in a cloud of cold atoms at low-light-levels when the incident optical fields simultaneously polarize, cool, and spatially-organize the atoms. We observe an extremely ...
  • 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 ...
