| Outline of Final Research Achievements |
Optical properties of silver mirror planar microcavities containing dye J-aggregates fabricated by a vacuum deposition were investigated. The dye-doped poly(vinyl sulfate) potassium salt film (PVS-K) showing very small Stokes shift of ～7.1 meV was regarded as suitable system for strong exciton-photon interaction. Reflectivity of ～59 % was obtained for the silver mirror microcavity by a reflectance measurement. Moreover, cavity-polariton formation was demonstrated for the J-aggregate-based low-Q microcavity. The Rabi-splitting energy of ～190 meV was responsible for the effective light confinement inside the silver mirror and a utilization of the J-aggregates showing small Stokes shift.
