We have fabricated organic semiconductor microcavities having an extended optical path-length (up to 2 µm) that contain J-aggregates of a cyanine dye. These structures are studied using optical-reflectivity and found be characterized by series polaritonic modes. By changing the effective oscillator strength dye within cavity, we evidence transition from “normal” strong coupling in which photon modes coupled one another via excitonic molecular state photon-modes become decoupled. use eight-level modified Hamiltonian describe properties system compare distribution confined field decoupled structures.
