contents We propose a serrated ultra-broadband infrared absorber based on the multi-layer repetitive stacking of indium tin oxide (ITO) and silicon materials. This absorber achieves continuously tunable absorption within a wide infrared light range. By changing the size and materials of the absorber, its average absorption rate can reach a relatively high level. Simulation results reveal wavelength-dependent electric field localization: shorter wavelengths concentrate in narrower upper regions, while longer wavelengths localize in wider lower areas. This design offers potential applications in near-infrared detectors, optical communication, and smart windows.
