Abstract
A device, for emitting and controlling infrared light, comprises a substrate extending between a bottom surface and a top surface. A cavity is provided in the substrate, the cavity opening onto the top surface. A light source extends over the cavity and is able to heat up when passed through by an electric current, so as to emit infrared light. A cover covers the substrate, the cover and the substrate forming a first component enclosing the light source. The light source delineates a first half space comprising the cover, and a second half space comprising the cavity and the bottom surface of the substrate.
