Terahertz topological photonic waveguide switch for on-chip communication
文献摘要：
Terahertz(THz)topological photonic structures are promising for last-centimeter communication in intra/in-terchip communication systems because they support bit-error-free THz signal transmission with topological robustness.Active and dynamically tunable THz topological photonic components have not yet been experimen-tally realized.Here,we experimentally demonstrate a THz topological switch(270-290 GHz)based on a valley Hall photonic crystal structured high-resistivity silicon substrate,in which the THz waves can be dynamically turned on/offby an external 447 nm continuous-wave laser.Our device exhibited an on/off ratio of 19 dB under a pumping light intensity of 240 mW/mm2.The 3 dB switching bandwidth was～60 kHz.
