Abstract:

Nonlinear optical response is reported 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 large polariton "Rabi"
splittings and modulated by near resonant fsec excitation pulses.
