Abstract
A bolometric detector including an absorption membrane, for converting an incident electromagnetic radiation into heat; and a reflector, for reflecting to the absorption membrane part of the incident electromagnetic radiation having passed there through, is provided. The bolometric detector includes a non-metallic layer, situated between the absorption membrane and the reflector, having a series of index jumps, so as to form a network resonating at a wavelength of interest λ0; the mean pitch of the network is less than λ0; and the optical distance between the absorption membrane and the reflector is substantially equal to a multiple of λ0/2.
