Abstract: An infrared IR radiation emission surface in a predetermined wavelength range comprises a substrate made of a material based on silicon carbide SiC, and an ensemble of texturing microstructures covering the exposed emission face of the substrate. Each microstructure is formed by a single protuberance, which is arranged on and integrally with the substrate. The microstructures have the same shape and the same dimensions, and are distributed over the face of the substrate in a bidimensional periodic pattern. The shape of each microstructure is smooth and regular, with a radius of curvature which varies continuously from the apex of the microstructure to the exposed emission face of the substrate.

Abstract: An antireflection optical surface, exhibiting absorption in the domain of the visible and of the near infrared, comprises a substrate made of a material based on silicon carbide SiC and a set of texturing microstructures carpeting an exposure face of the substrate. Each microstructure is formed by a single protuberance produced on and integral with the substrate.
