Abstract
Tunable Broadband Superradiance In article number 2200393, Zhengchen Liang, Hong Zhang, Wei Wang, and colleagues experimentally demonstrate a tunable broadband superradiance in 2D metal-dielectric-metal nanocavity arrays. Rationally designed 3-mode hybridization enables an emissive superradiant hybrid mode over a broadband visible range, with greatly shortened polariton lifetimes down to 4 femtoseconds. This may provide a potential strategy to promote efficient manipulation of light emission for applications requiring bright, fast-emitting photon sources.
