Abstract

Subwavelength metamaterial nanounits can efficiently harvest electromagnetic (EM) waves, resulting in near unity light absorption in the narrow or broad frequency range. For this purpose, we explored the material and architecture requirements for the realization of light perfect absorption using these metamaterial designs from ultraviolet (UV) to far-infrared (FIR) wavelength regimes. This, in turn, opens up the opportunity of the practical application of these perfect absorbers in large scale dimensions. We adopted these lithography-free techniques in many applications including photoelectrochemical water splitting, photodetection, light emission, sensing, filtering and thermal camouflage. This presentation will summarize our recent accomplishments in scalable photonic and photoelectronic designs for various applications.
