We have established a fabrication technique of a sprit ring resonator (SRR) tuned at the same resonance wavelength to that of a semiconductor quantum dot in the near infrared wavelength region. By using the nano-scale patterning with the anodic oxidation of substrate with an AFM probe tip or with the electron beam lithography methods, we can successfully control the position of the quantum-dots cluster with a ten-nanomenter scale near a SRR on the substrate. The significant enhancement of luminescence intensity was observed for the quantum dots near SRR structures compared with the luminescent intensity of the quantum dots without structures. We have also developed a numerical simulation program to analyze the electromagnetic interaction between the quantum dots and SRR and obtained useful information to understand experimental results.

我们建立了一种在近红外波段调谐与半导体量子点的共振波长相同的SPRIT环形谐振器(SRR)的制作工艺。通过利用AFM探针针尖对衬底进行阳极氧化的纳米级图案化或电子束光刻方法，我们可以成功地控制量子点团簇在衬底上SRR附近的10纳米尺度的位置。与无结构的量子点相比，SRR结构附近的量子点的发光强度有显著的增强。我们还开发了一个数值模拟程序来分析量子点与SRR之间的电磁相互作用，得到了有助于理解实验结果的有用信息。
