Microcavities with disordered organics

One of the unsolved problems arising in the framework of the macroscopic approach is the nature of the lowest energy local states in the microcavity with disordered organics. The nature of states which formally appear in the region of molecular resonance are clear they do not interact with the cavity photon and for this reason are similar to states in non-cavity organic material. However, the nature of cavity polaritons near the lowest end-points deserves careful... 

Ref. (15) made with the Rabi splitting and detuning 100 meV yielded, for microcavities with disordered organics, /cm n 104 cm-1. Then for the wavepackets satisfying 1 < f3l/2kmin < 10, the characteristic time would be 0.2 < tb < 20 ps and the corresponding velocity 5 108 > Vb > 5 107 cm/s. In our ID numerical example below we will use the value of parameter / within the segment just discussed. 

The numerical simulations performed in (32), (33) for one-dimensional microcavity containing organic material with diagonal disorder qualitatively confirm the conclusions made above on the structure of the polaritons spectrum in an organic microcavity. Future simulations for realistic 2D organic microcavities would be very topical.
