Functional mid-infrared metasurfaces for optical wavefront manipulation, sensing and dynamic phase control
2021
We present device applications of all-dielectric mid-infrared metasurfaces ranging from label-free biosensing and high precision spectral filtering to optical wavefront and polarization control. Additionally, we experimentally demonstrate how the concept of static Huygens’ metasurfaces can be extended with phase change materials to obtain spatial and active control of optical phase while maintaining high transmission efficiency.
