## Abstract A new type of optically controllable terahertz wave attenuator using highโresistivity silicon wafer is developed and tested. Without optical excitation, the highโresistivity silicon is a lossless dielectric material at terahertz wave region. When the highโresistivity silicon wafer is op

## Abstract In this letter, a novel terahertz (THz) wave switch based on metamaterial is proposed and measured.Onโoff switching is based on a controllable resonance of the metamaterial by applying an external semiconductor laser to illuminate substrate. Experimentally, we demonstrate onโoff respons
We demonstrated experimentally a terahertz wave modulator based on optically controlled metamaterial. The signal modulation mechanism of the presented terahertz wave modulator was based on the resonance characteristic of metamaterial controlled without or with light excitation. A modulated semicondu
We designed and demonstrated experimentally a terahertz wave switch utilizing microstrip resonator structure. The switch mechanism of the presented terahertz wave switch is based on the resonance charactersitic of resonator microstrip structure controlled by without or with light excitation. The exp
## Abstract We studied the design and characterization of an optically controlled terahertz (THz) wave modulator based on silicon photonic crystal slab, which is made from a highโresistivity Si with triangular lattice and a line defect formed by removing a single row of air holes along ฮโK directio
