| 研究開始時の研究の概要 |
I will propose a chiral metamirror to realize handedness switching. This chiral metamirror is applied to excite CPEs with opposite handedness at different emission angles. In contrast to the conventional methods, this work proposes a more efficient approach to manipulating the handedness of CPE.
|
| 研究実績の概要 |
I have published two journal articles on the topic of chiral metamaterial. In the first work, I propose an angle-sensitive chiral metamirror to realize handedness switching. In the second work, I report rod-shaped and ring-shaped metasurfaces capable of inducing narrowband transmission dips. These two works demonstrate the significant potential for advancing photonic devices.

1: 当初の計画以上に進展している
理由
I achieved my goals mentioned in the proposal smoothly and obtained high-quality results from my work. Finally, I successfully published two journal articles on "ACS Applied Materials& Interfaces" and "Applied Physics Letter", respectively.
|
| 今後の研究の推進方策 |
Since I have achieved the goals mentioned in the proposal, I will work on a new project in the future. In my new project, I will design a new structure for the realization of nanolaser with a large quality factor and long propagation length. For the design of structure, the numerical simulation will be conducted by using Comsol. For the fabrication of the structure, laser lithography will be conducted. Then, a home-built setup will be used for the measurement of lasing.
