  • ASYMMETRIC MIM TYPE ABSORBENT NANOMETRIC STRUCTURE AND METHOD FOR PRODUCING SUCH A STRUCTURE
    Publication number: 20130092211
    Abstract: According to one aspect, the invention relates to an asymmetric MIM type absorbent nanometric structure (1, 1?) intended to receive a wide-band incident light wave the absorption of which is to be optimised within a given spectral band, comprising an absorbent dielectric layer (10) in said spectral band, of subwavelength thickness, arranged between a metal array (11) of subwavelength period and a metal reflector (12).

  • Binary type diffractive optical elements for wide spectral band use
    Publication number: 20070103782
    Abstract: A binary type diffractive optical element for scalar optics uses a composite artificial material comprising, in a first portion Ma1, microstructures according to a first geometry for which the effective index decreases with the fill factor and, in a second portion Ma2, microstructures according to a second geometry for which the effective index increases with the fill factor. In one example, a composite artificial material is thus formed by hole type microstructures over a first portion, the smallest hole giving the maximum effective index value of said composite artificial material, and pillar type microstructures, the smallest pillar giving the minimum effective index value of said composite artificial material.
