Reconfigurable photoinduced terahertz wave modulation using hybrid metal–silicon metasurface

Ahasan Ullah, Yi-Chieh Wang, Sanjida Yeasmin, Yijing Deng et autres

We present a photoinduced reconfigurable metasurface to enable high spatial resolution terahertz (THz) wave modulation. Conventional photoinduced THz wave modulation uses optically induced conductive patterns on a semiconductor substrate to create programmable passive THz devices. The technique, albeit versatile and straightforward, suffers …
