OPTICALLY TRANSPARENT COMPONENT WITH TWO SETS OF CELLS
First Claim
1. A transparent optical component comprising a base optical component and two transparent sets of cells arranged in respective layers superposed on a surface of said base component, each cell containing an optically active material, and the cells in each set being isolated from one another by separating portions within the corresponding layer, parallel to the surface of the base component, the component being characterized in that a cell in each set is located in line with a separating portion pertaining to the other set of cells, along an axis perpendicular to the surface of the base component, with respective outlines for said cell and said separating portion that have substantially identical projections on the surface of the base component.

Abstract
A transparent optical component comprises two sets of cells (1) disposed in respective superposed layers (10, 20). Each cell (1) contains an optically active material, and the cells in each set are isolated from one another by separating portions (2) within the corresponding layer. The cells (1) of one layer are offset relative to the cells of the other layer so as to be located in line with the separating portions (2) pertaining to the other layer. Such optical component exhibits transparency that is improved compared with components having a single layer of cells or cells that are superposed.

22. A method of fabricating a layered transparent cell structure, the method comprising the following steps:
-
a) obtaining a transparent structure of superposed layers comprising, in order;
a first layer of lithographic resin, an additional layer that is absorbing for a radiation of a lithographic method suitable for etching the first layer of resin, and a second layer;b) forming a mask on said second layer, said mask defining the locations of cells to be formed; c) selectively removing portions of said second layer and of the additional layer as defined by the mask so as to form a first set of cells in said second layer and in said additional layer; d) filling the cells of the first set with at least one optically active material; e) after the mask has been removed, irradiating the first layer of lithographic resin through the second layer and the additional layer so that portions of said first layer that are located in line with cells of the first set become permanently fixed, selectively relative to portions of said first layer that are located in line with remaining portions of the additional layer; f) developing the first resin layer so as to form a second set of cells in said first resin layer; and g) filling the cells of the second set with optically active material. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)
