Polariton effect in a chain of coupled photonic dots

We investigate theoretically the spatial and temporal evolution of optical excitations in a chain of coupled identical semiconductor three-dimensional microresonators (photonic dots), whose frequency is neat the exciton-polar iton resonance in each dot. We show that the optical excitation of a single dot in a chain will be transferred laterally to neighboring dots with velo cities, depending on the exciton-photon detuning, Rabi frequency (character izing the exciton-polariton effect) and the overlap integrals between the p hotonic modes in neighboring dots.
