A detection device includes an absorbent first stack configured to absorb an electromagnetic radiation in at least a first wavelength range and presenting a first thermal expansion coefficient. It also includes a second stack forming an optical function and presenting a second thermal expansion coefficient. The first thermal expansion coefficient is different from the second thermal expansion coefficient and the detection device further includes a buffer layer separating the first stack and the second stack. The buffer layer presents a thickness included between 0.5 μm and 50 μm so as to absorb the mechanical stresses induced by the first stack.
