论文摘要
在本文中，我们证明了从GE（Si）量子点发出的红外光致发光发射，并通过硅纳米圆柱的集体MIE模式增强。我们表明，线性纳米阵列阵列的带缘偶极模式的激发导致光致发光光谱的重塑。在其他集体模式中，沿阵列轴具有极化的磁性偶极模式对发射光谱的贡献最大，该发射光谱表现出一个实验测量的Q因子，约为500架11个支柱。该结果属于采用集体MIE共振的量子发射器的光发射增强的第一个实验证据，因此代表了对新的活跃全元元元视频的新领域的重要贡献。
In this paper, we demonstrate the infrared photoluminescence emission from Ge(Si) quantum dots enhanced with collective Mie modes of silicon nanopillars. We show that the excitation of band edge dipolar modes of a linear nanopillar array results in strong reshaping of the photoluminescence spectra. Among other collective modes, the magnetic dipolar mode with the polarization along the array axis contributes the most to the emission spectrum exhibiting an experimentally measured Q-factor of around 500 for an array of 11 pillars. The results belong to the first experimental evidence of light emission enhancement of quantum emitters applying collective Mie resonances and therefore represent an important contribution to the new field of active all-dielectric meta-optics.
