Sb2S3 Mie-resonant dielectric metasurfaces for tunable near infrared filtering
Abstract
The field of metasurface optics is well-suited to leverage advanced materials due to their unique ability to tailor light–matter interactions at the sub-wavelength scale, providing a high degree of dynamic functionality. In this Letter, we explore the low-loss chalcogenide-based phase change material Sb2S3 and its integration into Mie-resonant metasurfaces to realize highly tunable near-infrared transmission-based filters. Through a combination of computational modeling, fabrication, and characterization of near-infrared Sb2S3 metasurfaces, we demonstrate spectrally selective filters with high optical densities that achieve an absolute optical transmitted contrast of over 80% via thermal stimulus. Our work highlights the potential for reversible non-volatile optical writing and color filtering, tunable both passively and actively.
