Patent application numberDescriptionPublished
20080278815ISOTROPIC ZERO-ORDER DIFFRACTIVE FILTER - The present invention relates to an isotropic zero-order diffractive colour filter, to a method to manufacture an embossing tool and to a method to manufacture such a filter.11-13-2008
20090038683Method and Apparatus for Patterning a Conductive Layer, and a Device Produced Thereby - A device is fabricated by a method in which a conductive layer or layer stack is formed over a compressible layer or layer stack, and contacted with an embossing tool. Raised portions of the embossing tool compress the compressible layer or stack and countersink the conductive layer or stack into the compressible layer or stack.02-12-2009
20090257126ZERO-ORDER DIFFRACTIVE PIGMENTS - 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.10-15-2009
20090263071Optical environmental sensor and method for the manufacturing of the sensor - 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.10-22-2009
20100148159METHOD FOR FORMING A PATTERN ON A SUBSTRATE AND ELECTRONIC DEVICE FORMED THEREBY - The invention relates to a method for forming a pattern on a substrate (S) with an upper surface and a lower surface which comprises the steps of depositing a first layer (E06-17-2010
20100315713ZERO-ORDER DIFFRACTIVE FILTER AND METHOD FOR MANUFACTURING THEREOF - The present invention discloses a method for manufacturing a zero-order diffractive filter comprising a high-index material having an upper surface and a lower surface. The high-index material is positioned between a first low-index matter and a second low-index matter; the lower surface is adjacent to said first low-index matter and the upper surface is adjacent to the second low-index matter. Moreover, the high-index material has an index of refraction that is higher than the index of refraction of both said first low-index matter and said second low-index matter. The method comprises at least the following procedure: selectively providing, by employing at least one wet-coating technique, at least one of the following at least partially: the high-index material onto said first low-index matter.12-16-2010
20110008399USE OF ZERO-ORDER DIFFRACTIVE PIGMENTS - The present invention relates to compositions such as coatings, printing inks or cosmetics, which contain 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.01-13-2011
20110317268ZERO-ORDER DIFFRACTIVE PIGMENTS - 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.
