The invention relates to a device for detecting a gaseous species by photoacoustic effect. The device comprises a substrate, inside which a cavity is formed. A light source is disposed on the substrate, in such a way that a part of the substrate extends between the light source and the cavity. The device is arranged in such a way that the light, emitted by the light source, is propagated through the substrate, before reaching the cavity.

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.
