Topology-Enabled Switchable Unidirectional Radiative Band in a Bilayer Photonic Crystal
Zhiyi Yuan, Vytautas Valuckas, Yuhao Wang +6
Controlling how an open photonic system exchanges energy with its environment-and in particular how it radiates into the far field-is a cornerstone of non-Hermitian wave physics an…

Dual-resonance nanostructures for colour down-conversion of colloidal quantum emitters
Son Tung Ha, Emmanuel Lassalle, Xiao Liang +9
Linear colour conversion is a process where an emitter absorbs a photon and then emits another photon with either higher or lower energy, corresponding to up- or down conversion, r…
