We report observation of dispersion for coupled exciton-polariton in a plate microcavity combining with ZnO/MgZnO multi-quantum well (QW) at room temperature. Benefited from the large exciton binding energy and giant oscillator strength, the room-temperature Rabi splitting energy can be enhanced to be as large as 60 meV. The results of excitonic polariton dispersion can be well described using the coupling wave model. It is demonstrated that mode modification between polariton branches allowing, just by controlling the pumping location, to tune the photonic fraction in the different detuning can be investigated comprehensively. Our results present a direct observation of the exciton-polariton dispersions based on two-dimensional oxide semiconductor quantum wells, thus provide a feasible road for coupling of exciton with photon and pave the way for realizing novel polariton-type optoelectronic devices.

基于ZnO / MgZnO量子阱的激子-极化子在室温下的色散

我们报告了在室温下与ZnO / MgZnO多量子阱（QW）相结合的平板微腔中耦合激子-极化子耦合的色散观察。得益于大的激子结合能和巨大的振子强度，室温拉比分裂能可以提高到60 meV。使用耦合波模型可以很好地描述激子极化子色散的结果。结果表明，极化波分支之间的模式修改仅通过控制泵浦位置就可以在不同的失谐中调谐光子分数，这可以得到全面研究。我们的结果直接观察了基于二维氧化物半导体量子阱的激子-极化子色散，
