Abstract

Ultrathin, all-dielectric, metamaterial design based on an asymmetrical optical micro-/nanocavity, enclosing a 10 nm thick Ge2Sb2Te5 photoabsorber film, is inversely optimized for perfect tunable absorption in the mid-infrared. The absorption can be actively/geometrically pre-/post-fabrication spectrally tuned.
