Topological crystals are a revolutionary class of materials that exhibit unique electronic and physical properties due to their non-trivial topological band structures. These materials have garnered ...

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...

Topological photonics promises robust light transport immune to disorder, but existing linear systems are essentially static and cannot be reconfigured after fabrication. Now, a collaboration of ...
