Versatile Control of Spectral Emissivity in Mid‐Infrared Metasurfaces via Silicon Microstructuring

Advanced Optical Materials, EarlyView.
A family of metasurfaces is obtained very simply, solely through the structuration of a single‐crystal silicon surface, without any other material involved. Based on the infrared plasmonic behavior of highly doped silicon, further control of surface topography by micro‐ and nano‐structuration is found to enable an avenue of options toward tailoring its

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
