BROADBAND LIGHT ABSORPTION USING METALLIC NANOWIRE BASED PERFECT ABSORBERS

Abstract

Resonant plasmonics enable us to control the fundamental optical processes like absorption, emission and refraction at nanoscale. Cutting down the Fresnel Losses in nanophotonics is a challenge. Metal – insulator – metal stack in which nanostructured top silver film is designed in which metallice nanowire based (60 nm and 120 nm) super absorber yields broadband and TM and TE polarization exited resonant light absorption over the entire visible spectrum (400 – 700 nm) with an average measured absorption of 0.95.
