Switchable high-Q light absorbers based on phase-change resonant metasurfaces
Kai Qi, Guoxiang Wang, Xiang Shen +1
In this paper, we propose a switchable high-Q light absorber based on a reconfigurable metasurface enabled by a lowloss phase-change material (PCM). By leveraging the coupling betw…

Compact polarization-independent non-volatile optical switches
Fangfa Bao, Jiakai Ruan, Weijia Li +4
Compact, non-volatile optical switches on silicon platforms are essential for reconfigurable photonics, but the strong anisotropy of silicon waveguides leads to polarization-depend…

Degenerate merging BICs in resonant metasurfaces
Yixiao Gao, Junyang Ge, Zhaofeng Gu +3
Resonant metasurfaces driven by bound states in the continuum (BIC) offer an intriguing approach to engineer high-Q resonances. Merging multiple BICs in the momentum space could fu…
