| Research Abstract |
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.
