Outline of Research at the Start

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.

Outline of Annual Research Achievements

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.

Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

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.

Strategy for Future Research Activity

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.
