The spontaneous emission rate of an atom in dielectric slabs is shown to exhibit multiperiodic oscillations when the system scale is varied. These oscillations are calculated using quantum electrodynamics and analyzed using ideas from closed-orbit theory. The extracted frequencies in the emission rates by Fourier transform agree well with actions of short photon closed orbits. The oscillations in the spontaneous emission rates are interpreted as interferences of emitted photon propagating on closed orbits leaving and returning to the emitting atom. This study provides a new understanding of the spontaneous emission process for atoms in the presence of environments.

The angular distribution of the radiation emitted from a dye molecular solution in a planar symmetrical microcavity terminated by two high-reflectivity dielectric mirrors has been investigated. A quantum-mechanical analysis of this process was applied to a microcavity terminated by mirrors bearing dielectric multilayered coatings, whose optical parameters are calculated by means of the Lissberger–Wilcock algorithm. The experiment was performed for different polarizations of the pump beam and of the emitted radiation. The angular distribution of the spontaneous emission is strictly dependent on the behavior of the reflectivity and the phase of the mirrors relative to the angle of incidence. This restriction limits the microcavity confinement to relatively small values of the internal angle of emission.

We show that resonant dipole-dipole interactions are suppressed at all interatomic or intermolecular separations in periodic dielectric structures in which spontaneous emission is inhibited at the resonant optical transitions. This profoundly modifies molecular properties including donor-acceptor energy transfer, collisional dynamics, molecular spectra, and dissociation energies.
