摘要：
We have investigated the exciton-polariton condensation in a CuBr microcavity with HfO2/SiO2 distributed Bragg reflectors, focusing on condensation effects on polariton dispersion relations. The polariton distribution as a function of in-plane wave vector k under illumination was measured with angle-resolved photoluminescence (PL) spectroscopy. In addition, we characterized the intrinsic polariton dispersion relations as reference data from analysis of the results obtained using angle-resolved reflectance spectroscopy. It was found that the polariton condensation causes a large blueshift of the lower polariton branch (LPB) and a flat dispersion relation around the ground state at k(#)=0. The renormalized dispersion relation of the LPB under the polariton condensation was quantitatively analysed using a theory for a diffusive Goldstone mode peculiar to nonequilibrium condensation.
