Journal: | Applied Physics Letters | Abstract: | 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 reflectivity trough can be tuned to four different infrared (IR) wavelengths from 1906 to 2960nm by heating the structure to different temperatures. The near-perfect absorber is reconfigurable, lithography-free, industrially scalable, polarization-insensitive, and omnidirectional. Our strategy opens a path for programmable infrared photonics. | URI: | https://hdl.handle.net/10356/152954 | ISSN: | 0003-6951 | DOI: | 10.1063/5.0058384 | Rights: | © 2021 Author(s).
