In article number 1900338 by Tian Jiang and co‐workers, the resonance frequency tuning of electromagnetically induced transparency (EIT) is achieved by molecularizing silicon‐hybrid metasurfaces. The cover image shows the structure, where an all‐optical switching approach is used to realize an ultrafast EIT frequency shift at the THz regime. The proposed concept endows metaphotonic devices with advanced functionalities, providing a new opportunity for the metasurface‐based applications, such as high‐speed wireless communications, multiband sensors.
