Broadband Epsilon-Near-Zero Perfect Absorption in the Near-Infrared

Abstract

Perfect absorption (PA) of incident light is important for both fundamental light-matter interaction studies and practical device applications. PA studies so far have mainly used resonant nanostructures that require delicate structural patterning. Here, we realize tunable and broadband PA in the near-infrared region using relatively simple thin film… (More)
