Abstract

Modern imaging systems can be enhanced in efficiency, compactness, and range of applications through introduction of multilayer nanopatterned structures for manipulation of light based on its fundamental properties. Metaoptical components can be tailored to respond to these varying electromagnetic properties, but have been mostly explored in single-layer, ultrathin geometries, which limits their capacity for multifunctional behavior. Here we show the design of scattering structures which sort light efficiently based on its wavelength, polarization state, and spatial mode. The multispectral and polarimetry devices are further fabricated via two-photon lithography and experimentally validated in the mid-infrared.
