Strongly coupled organic microcavities with vibronic progressions

The optical properties of an organic polycrystalline film of NTCDA with one vibronic replica, embedded in a microcavity, were measured by Holmes and Forrest in 2004. They observed strong exciton-photon coupling and hybridization between the cavity mode and both the 0-0 and 0-1 vibronic transitions. The purpose of this work is to build a model to describe optical spectra of an organic, microcavity with vibronic replicas in both weak and strong coupling regimes between photon and exciton modes. The problem has been handled with two approaches, a microscopic model and a macroscopic one. The active material vibronic spectra have been calculated in-the Franck-Condon framework. With these models we have reproduced the experimental spectra and we have: also analyzed more complicated systems such as monocrystalline materials, (C) 2008 WILEY-VCH Verlag GmbH & Co.
