The active modulation of flexible terahertz tube
Source abstract
Abstract
Abstract We demonstrated a flexible polyimide terahertz tube that can modulate Terahertz (THz) wave efficiently based on indium oxide (In2O3) nanoparticle. The transmission of the THz pulse can be modulated using optical control over 0.2 to 2.6 THz, and the modulation depth reached up to 14%. By combining nano-indium oxide layer with metal periodic metamaterial structure, the modulation was optimized to 35%. The results show that a photo-excited tunable terahertz modulator can be realized by irradiating the structure under different intensity of the laser beam.
