When molecules are placed in the vicinity of photonic/plasmonic environments, the usual selection rules for light emission no longer prevail. Because of the electromagnetic field confinement, the molecular luminescence strongly gets enhanced, and dipole forbidden transitions may further be observed.

To predict the light emission of an emitter in such an environment, a new formalism which considers the rapid variation of the electromagnetic field within the spatial extent of the emitter is needed.

To do so, the photonic Green’s function of the environment must be computed and combined with the wavefunction of the emitter. The formalism is still under development but had already been verified for the case of Hydrogen.
