Cavity Polaritons in Organic Microcavities
Cavity Polaritons in Organic Microcavities
This chapter discusses the specific properties of excitations in microcavities with crystalline as well as with amorphous organics. For organic microcavities, it is typical that the very large Rabi (of order of 100 meV) splitting has a strong influence on the temperature stability of organic cavity polaritons spectra. The coexistance of coherent and incoherent (localized) states of polaritons for microcavities with disordered organics is demonstrated. The dependence of polariton spectra on values of Davydov and Rabi splittings is calculated for microcavity with crystalline organics. The coexistance of localized and coherent states of cavity polaritons is demonstrated by numerical simulations that consider the model of 1D microcavity with diagonal disorder. For such a model, the comparison of the dynamics of low-energy wave packet in perfect and in disordered microcavity is performed.
