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.

我们已经建立了一种在与近红外波长区域中半导体量子点相同的共振波长调谐的Sprit环共振器（SRR）的制造技术。通过使用AFM探针尖端或电子束光刻方法的底物氧化的纳米尺度图案化，我们可以成功地控制量子点簇的位置，该量子点簇的位置在srr附近，在底物附近， 。与没有结构的量子点的发光强度相比，SRR结构附近的量子点的发光强度显着增强。我们还开发了一个数值仿真程序，以分析量子点与SRR之间的电磁相互作用，并获得了有用的信息以了解实验结果。
