A bifunctional MoSe 2 ‐hybrid metadevice is judiciously designed to multidimensionally manipulate the resonant property via both incident angle and photo‐injection. The incident direction‐induced C 2 symmetry‐break leads to the resonance transition from LC to EIT‐like mode, and then each incident angle‐dependent resonance state is efficiently switched‐off with an ultrafast ...
