Visible to Infrared Dielectric Metasurfaces and their Applications

Dielectric metasurfaces, two-dimensional variant of metamaterials, have received significant attention from the scientific community due to enormous potential and ability to cater to various spectral bands of the electromagnetic spectrum and pave the way to achieve multi-functionalities in a single device, which was not possible earlier. Dielectric metasurfaces have the edge over their metallic counterparts in terms of zero-ohmic propagation losses, high efficiency, or ultra-high-quality factor and are compatible with existing CMOS technology. They support both electric and magnetic resonances in the optical domain. Here, we provide a comprehensive review of dielectric metasurfaces, encompassing visible to far-infrared wavelength regions, and discuss selective applications which may find its commercial value in the near future. Finally, we provide an outlook and perspective on dielectric metasurfaces for nonlinear and quantum applications.
