As an important mechanism of population transfer, we discuss Foerster resonance energy Transfer (FRET) which has found wide applications in chemistry and biology. For example, FRET is used to measure interactions between proteins or distances inside them. Furthermore it is hoped that this effect leads to new opportunities for manipulating and storing information in optical circuits.
We analyze FRET in a model system consisting of a 1D optical wire and two atoms, modeled as 2- level systems. We analyze the spectrum of the problem using tools from Quantum Field Theory. From this results we argue that there are very general reasons that FRET in 1D is a truly non Markovian effect and is mediated by the polaritonic eigenmodes of our model system which occurrence strongly depends on the curvature and boundedness of the dispersion relation of the waveguide. This shows that linearization of the spectra may be insufficient to catch essential physical features of this systems.
A possible interesting application of our result could be in light harvesting complexes which are important for the design of organic solar cells.
