Exciton-polariton dynamics in a transparent organic semiconductor microcavity

Exciton-polariton dynamics are studied in organic semiconductor microcavities operating in the strongly coupled polariton regime, with thin films of cyanine J-aggregates sandwiched between low-loss dielectric mirrors. The delocalized excitons are subject to polariton normal mode splittings which are modulated by near resonant femtosecond excitation pulses, while orientational disorder effects on the formation of polariton states play an important role in polariton dynamics.
