A four-state programmable mid-infrared band-stop filter exploiting a Ge₂Sb₂Te₅ film and VO₂ nanoparticles
We designed and demonstrated a four-state programmable mid-infrared band-stop absorber that exploits two different phase-change materials. This programmability is possible by exploiting Fabry–P erot resonances in a Ge2Sb2Te5 film and vanadium dioxide nanoparticles’ (VO2 NPs) dual layer. The reflecti...
