摘要
We report on the observation of polariton lasing in a negative detuned ZnO hybrid microcavity at room temperature (300 K) with threshold of 12.38 μJ/cm 2 and at high temperature (353 K) with a higher threshold of 53.05 μJ/cm 2 due to a stronger thermal escape process and a shallower polariton trap. The decoherence mechanism of the polariton laser due to the polariton self-interaction was investigated by power-dependent photoluminescence and Michelson interference measurements. The spatial coherence length r c ~ 0.26 μm of the polariton laser was obtained from Young's double slits.
