Abstract

Mid infrared metasurfaces is one of the key technology for sensors, energy harvesters in renewable society. Especially absorption type of metasurfaces can be applied for mid infrared light source and detectors according to Kirchhoff's law. Here we demonstrate the recent advances of metasurface, fabrication (lithography/lithography free), optical characterization of reflection ,scattering and absorption, photo-thermal energy conversion, and sensing applications in mid infrared wavelength. The experimentally measured optical properties were compared with simulations by finite difference time-domain (FDTD) method and finite element method (FEM).
