Giant Rabi splitting in organic microcavities

We mentioned here the strong coupling of a 2D electromagnetic wave (surface wave) and a 2D excitation because, as could be expected from the general 

Dispersion relation for an organic microcavity with a 20 nm thick NTCDA active layer. The broken curves are the uncoupled cavity photon (P) and Frenkel exciton (X) dispersion relations as determined by the fitting parameters. Inset room temperature photoluminescence and absorbance spectra for a 50 nm thick film of NTCDA. Absorption peaks at 3.19 and 3.39 eV are designated as the 0-0 and 0-1 transitions.

In the following sections of this chapter we consider in more detail the properties of excitations in organic microcavities with crystalline as well as with amorphous materials.
