Spatially localized but electromagnetically coupled electrons are model systems for excitation transfer on nanoscales. A unified description of coupled semiconductor quantum dots and coupled cholorophylls in light harvesting complexes is presented, considering Coulomb interaction including excitonic Forster-coupling and (bi-) excitonic shifts as well as electron-phonon interaction. Linear absorption spectra are calculated and principles for the description of third order optical nonlinearities are outlined.
