文章采用AlxGa1-xAs／AlyGa1-yAs微腔结构，研究了微腔中激子的吸收行为，在室温下观察到了激子吸收的增强效应，激子的峰值吸收强度是自由空间中激子吸收强度的2，6倍；我们从激子与光波场相互作用和腔中模函数的分布建立了计算．激子先吸收的模型，文中给出的微腔结构的数值计算表明激子的吸收增强与实验结果相一致；数值计算表明，微腔中激子吸收的强弱不仅与上、下两腔镜的反射率和腔长有关，而且还取决于量子阱在腔中的位置．
In this paper, the absorption behavior of excitons in microcavities was studied by using AlxGa1-xAs / AlyGa1-yAs microcavity structure. The enhancement effect of exciton absorption was observed at room temperature. The peak absorption intensity of excitons is the intensity of exciton absorption in free space Of the 2,6 times; we set up the calculation from the interaction between the exciton and the light wave field and the distribution of the mode functions in the cavity. Exciton first absorption model, the numerical calculation given in the microcavity structure shows that the exciton absorption enhancement consistent with the experimental results; numerical calculations show that the strength of excitons in the microcavity not only with the upper and lower endoscopic The reflectivity and cavity length, but also depends on the quantum well in the cavity position.
