We performed the research aiming at the realization of optical interconnection using Yagi-Uda antennas. (1)We realized a measurement of radiation pattern from optical Yagi-Uda antennas in a homogeneous medium using liquid immersion method and succeeded in a quantitative evaluation of the fundamental parameters such as the directional gain and half-angle radiation, for the first time. (2)We embedded optical Yagi-Uda antennas in a planar dielectric waveguide as an approach to planar optical circuit technology. It was found that the radiation and reception gain of 5-element antenna is about 4. In addition, a gain as high as 15 was demonstrated in the interconnection between the Yagi-Uda antennas in the waveguide. (3)Toward the control of spontaneous emission from quantum dots by Yagi-Uda antennas, a method of immobilize quantum dots on a gold pattern was established. The quantum dots were successfully immobilized on a 100 nm square region.

我们进行了研究，旨在实现光互连使用八木宇田天线。(1)We利用液体浸没法实现了均匀介质中光学八木宇田天线辐射方向图的测量，并首次成功地定量评价了天线的方向性增益和辐射半角等基本参数。(2)We在平面介质波导中嵌入光学八木宇田天线作为平面光路技术的方法。结果表明，五单元天线的辐射和接收增益约为4。此外，在波导中的八木宇田天线之间的互连中展示了高达15的增益。（3）针对Yagi-Uda天线对量子点自发辐射的控制，建立了一种在金图案上覆盖量子点的方法。量子点被成功地固定在100 nm的正方形区域上。
