Resonance Fluorescence

  • Participants: Geesche Boedecker and C. Henkel


'Resonance fluorescence' is the radiation emitted by an atom that is driven by a laser field. The calculation of its spectrum is one of the cornerstones of quantum optics.
  • We are studying the resonance fluorescence from a single emitter embedded in a photonic crystal, when the atomic transition frequency is close to the edge of a photonic band. In that case, the atom is strongly correlated to a 'cloud' of photons localized nearby, and the backscattering of the photons significantly changes the dynamical behaviour of the field. We are solving a non-Markovian master equation for the two-level emitter.
  • A review of spontaneous emission in a photonic crystal can be found in a chapter of the book "Photonic Crystals" (edited by K. Busch, S. Lölkes, R. B. Wehrspohn, and H. Föll, Wiley-VCH). (Link to the publication.)
  • In a previous paper, we have developed a simple method to describe the light field in a one-dimensional periodic structure of finite thickness. (Link to the paper.)
