    • Controllable ultrabroadband slow light in a warm rubidium vapor 

      Fischer, MC; Gauthier, Daniel J; Greenberg, JA; Zhang, R (Journal of the Optical Society of America B: Optical Physics, 2011-01-01)
      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 absorption ...
    • Measurements of nonlinear refractive index in scattering media. 

      Samineni, P; Perret, Z; Warren, WS; Fischer, MC (Opt Express, 2010-06-07)
      We have recently developed a spectral re-shaping technique to simultaneously measure nonlinear refractive index and nonlinear absorption. In this technique, the information about the nonlinearities is encoded in the frequency ...
