3D Meta-Optics for Sorting Light and Image Processing

35 words abstract: Structuring optical properties with a spatial resolution much smaller than the relevant wavelength of light leads to optical structures with non-intuitive optical response. I discuss our recent progress in designing and fabricating these structures.

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. I discuss several recent implementations of this type of devices for sorting light based on wavelength, polarization and spatial modes. Then I present devices for optical image processing like edge detection with enhanced optical bandwidth. Implementations at mid infrared and shorter wavelengths is discussed.
