Simplified calculation of dipole energy transport in a multilayer stack using dyadic Green's functions.

We extend the model of Chance, Prock and Silbey [1] and analytically determine the Poynting vector in the direction perpendicular to the plane of a multilayer organic device. The result is used to predict the spatial profile of Förster energy transfer, the radiative output of an organic light emitting device, and to calculate the efficiency of surface plasmon polariton-mediated energy transfer across a thin silver film.
