Abstract
Strong exciton-photon coupling in an optical microcavity containing a thermally evaporated polycrystalline organic thin film were investigated. Coupling between the 0-0 excitonic transition of 3,4,7,8 napthalenetetracarboxylic dianhydride and a cavity photon resulted in microcavity polaritons. It was suggested that in addition to exhibiting large Rabi splittings, thermally evaporated polycrystalline films provide a means for understanding effects of morphology and long range order on the strongly coupled state. The observation of strong coupling in polycrystalline materials was suggested to allow for increased phonon assisted relaxation to the zero wave vector state as a result of enhanced phonon coupling in the film.
