Polarization-Orthogonal Nondegenerate Plasmonic Higher-Order Topological States
Yuanzhen Li, Su Xu, Zijian Zhang +10
Photonic topological states, providing light-manipulation approaches in robust manners, have attracted intense attention. Connecting photonic topological states with far-field degr…

Controlling high-Q trapped modes in polarization-insensitive all-dielectric metasurfaces
Andrey Sayanskiy, Anton S. Kupriianov, Su Xu +4
We reveal peculiarities of the trapped (dark) mode excitation in a polarization-insensitive all-dielectric metasurface, whose unit super-cell is constructed by particularly arrangi…
