Original Abstract

The development of metasurfaces offers many novel optical functions provided by precisely fabricated nanostructures. One can tune the metasurface functionality after its fabrication by incorporating phase-transition materials. Vanadium dioxide (VO2), which undergoes the volatile dielectric-metallic phase transition, offers such potential for tunability already around 67°C. Here, we focus on the alignment of the dielectric and plasmonic resonances of VO2 nanostructures at near-infrared wavelengths. Such resonance alignment, which can be applied to a tunable perfect absorbing grating, is demonstrated on an array of VO2nanostructures.
