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.
