Paper Abstract

We experimentally demonstrate a multispectral metasurface that exhibits controlled inhomogeneous optical properties leading to a spatial modulation of the emissivity up to the wavelength scale in the infrared. A metasurface made of a non-periodic set of 100 million optical nano-antennas that spatially and spectrally control the emitted light up to the diffraction limit has been realized and studied. Each antenna acts as an independent deep subwavelength emitter for a given polarization and wavelength, and their juxtaposition at the wavelength scale can encode far field multispectral and polarized images.
