The relative intensity of photonic modes in microcavity pillars with embedded self-assembled quantum dots is shown to be a sensitive function of quantum dot dipole orientation and position. This is deduced from a comparison of experiment and calculated intensities of light emission for many nominally identical pillars. We are able to obtain the overall degree of in-plane polarization of the quantum dot ensemble and also to obtain information on the degree of polarization along the growth axis.
嵌入自组装量子点的微腔柱中光子模式的相对强度被证明是量子点偶极子取向和位置的敏感函数。这是通过对许多名义上相同的柱体的光发射实验强度和计算强度进行比较得出的。我们能够获得量子点系综的面内极化的整体程度,还能获得沿生长轴的极化程度的信息。
