  • Publication number: 20090263071
    Abstract: A sensor which reacts on influences from an environment. The sensor includes a zero-order diffractive color filter. The zero-order diffractive color filter includes a high-index waveguide layer, a zero-order diffractive grating structure and a layer of an reactive material, wherein the reactive material is in contact with the environment and wherein the reactive material changes its optical properties upon interaction with the environment. The reactive material is embedded in the waveguide layer and/or the reactive material is located at a maximum distance d from the waveguide layer. The distancing is effected by an intra layer having a low index of refraction.

  • Publication number: 20090257126
    Abstract: The present invention relates to pigments comprising or consisting of a layer made of a material with an index of refraction that is higher than the index of refraction of the adjacent material by at least 0.25; whereas said layer has a zero-order diffractive micro-structure; whereas said layer acts as an optical waveguide and whereas said layer has a thickness between 50 nm and 500 nm; to processes for its manufacture and to its use. These pigments show a colour effect upon rotation and/or tilting, and it is believed that this colour effect is based on zero-order diffraction.
