Exciton-polariton states that arise from strong coupling of hybridized Frenkel and Wannier-Mott excitons with cavity photons are theoretically predicted [1,2] to exhibit large radius, small saturation density and large oscillator strength at the same time. These new features should strongly favorite observation of non-linear phenomena and overcome intrinsic limitation of both type of semiconductors. Here we fabricate and study a multilayered structure that combines GaAs QWs and molecular J-aggregate cyanine dye in a high Q planar microcavity. Strong coupling regime is achieved due to interaction of both exciton species with the cavity photons. The implementation of a light emitting diode design with electrical pumping of excitons in the inorganic QWs would be especially significant for both optoelectronic device applications (electrically pumped organic polariton laser) and fundamental studies of exciton dynamics in a microcavity system.
