'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,
In a previous paper, we have developed a simple method to
describe the light field in a one-dimensional periodic
structure of finite thickness.
