Abstract

Photoluminescence (PL) properties of polaritons at room temperature were investigated in a two-dimensional array of inorganic-organic hybrid-type semiconductor quantum-wells. In angularly-resolved PL spectra, PL peaks attributed to the lower branch of polariton shift with a detection angle and show a great change of its intensities. The central energy of PL peak at a certain detection angle is connected by the dispersion relation of the polariton, which is much different from polaritons in a bulk semiconductor. PL intensity of polariton is significantly enhanced at a half of Rabi splitting energy lower than exciton resonant energy due to the polariton bottleneck effect. PL intensity around Γ point is found to be strongly modulated depending on material parameters of the samples.
