Experimental observation of strong light-matter coupling in ZnO microcavities: influence of large excitonic absorption
摘要:
我们目前的实验观察,在硅上生长的ZnO体微腔的强光-物质耦合制度。角分辨反射率的测量,证实了传输矩阵模拟,表明拉比分裂的顺序为70毫电子伏的实现,即使是低精细腔。大的激子吸收的影响,这使得ZnO的散装状的行为,即使在强耦合制度,实验和理论上说明考虑腔厚度增加。
英文摘要:
We present experimental observation of the strong light-matter coupling regime in ZnO bulk microcavities grown on silicon. Angle resolved reflectivity measurements, corroborated by transfer-matrix simulations, show that Rabi splittings in the order of 70 meV are achieved even for low finesse cavities. The impact of the large excitonic absorption, which enables a ZnO bulk-like behavior to be observed even in the strong coupling regime, is illustrated both experimentally and theoretically by considering cavities with increasing thickness.
