Abstract:
According to one aspect, the invention relates to an optical security component intended for being observed under direct reflection. The component comprises a structure engraved on a layer of a material having a refraction index n 2 , a thin layer of a dielectric material having a refraction index n 1  other than n 2 , deposited on the structure, and a layer of a material having a refraction index no other than n 1 , encapsulating the coated structure of the thin layer. The structure has a first pattern modulated by a second pattern such that, in at least one first region ( 61, 86 ), the first pattern comprises a low-relief with a first set of facets, the shapes of which are determined such as to generate at least one first concave or convex cylindrical reflective element, and the second pattern forms a first subwavelength grating acting, after depositing the thin layer and encapsulating the structure, as a first wavelength-subtractive filter; in at least one second region ( 62, 86 ), the first pattern comprises a low-relief with a second set of facets in which the shapes are determined such as to generate at least one concave or convex cylindrical reflective element ( 64 ), and the second pattern forms a second subwavelength grating acting, after depositing the thin layer and encapsulating the structure, as a second wavelength-subtractive filter, separate from the first wave-length-subtractive filter. Each subwavelength grating can be a zero order diffraction grating such as a DID.

Claim (Index 8):
The optical security component as claimed in  claim 4 , in which, in a third region situated in proximity to the central facets of the first and second sets of facets, the first pattern of the structure is formed of a plane surface parallel to the first and second central facets and the second pattern forms one or more sub wavelength gratings acting, after deposition of the thin layer and encapsulation of the structure, as one or more wavelength-subtractive filters.
