Abstract
An active ultraviolet light-induced terahertz modulation based on indium oxide thin film was investigated in which exhibit a large absorption modulation of ~50% when illuminated by a low intensity UV laser (11 mW/cm2). The interaction between indium oxide and the metamaterial structure was investigated due to the large enhancement of photo carriers in UV-induced in indium oxide film. We can realize the absorption peak shifts of 37 GHz by changing the UV excited light intensity.
