Spatiotemporal Lineshape Tailoring in BIC‐Mediated Reconfigurable Metamaterials (Adv. Funct. Mater. 34/2022)

Spatiotemporal Lineshape Tailoring In article number 2203680, Tian Jiang and co-workers demonstrate a novel reconfigurable metasurface supporting a symmetry-protected bound state in the continuum in the electromagnetic induced transparency window. With active media embedded in the proposed metasurface, spatiotemporal lineshape tailoring with resonance mode conversion and ultrafast amplitude switching is successfully achieved, which is appealing for next-generation flat photonic devices with high-compact, functionality-integrated, and fast-speed properties.
