Realizing topologically protected ghost surface polaritons by lattice transformation optics

Autor: Kong, Xianghong, Hu, Chuanjie, Liu, Xingsi, Zheng, Chunqi, Chen, Jianfeng, Chen, Huanyang, Qiu, Cheng-Wei

While conventional surface waves propagate along the surface and decay perpendicularly from the interface, the ghost surface polaritons show oblique propagation direction with respect to the interface. Here, we have discovered topologically protected

Negative reflection and negative refraction in biaxial van der Waals materials

Autor: Zhang, Tan, Zheng, Chunqi, Chen, Zhi Ning, Qiu, Cheng-Wei

Negative reflection and negative refraction are exotic phenomena that can be achieved by platforms such as double-negative metamaterial, hyperbolic metamaterial, and phase-discontinuity metasurface. Recently, natural biaxial van der Waals (vdW) mater

Report

Tailoring topological transition of anisotropic polaritons by interface engineering in biaxial crystals

Autor: Zeng, Yali, Ou, Qingdong, Liu, Lu, Zheng, Chunqi, Wang, Ziyu, Gong, Youning, Liang, Xiang, Zhang, Yupeng, Hu, Guangwei, Yang, Zhilin, Qiu, Cheng-Wei, Bao, Qiaoliang, Chen, Huanyang, Dai, Zhigao

Polaritons in polar biaxial crystals with extreme anisotropy offer a promising route to manipulate nanoscale light-matter interactions. The dynamical modulation of their dispersion is great significance for future integrated nano-optics but remains c
