An array of sensing pixels (100) detects infra-red radiation of two or more wavelengths. Each sensing pixel (100) includes at least two different quantum-well sensing stacks (110, 120) that are biased at a common voltage (Vbias).

Un réseau de pixels (100) de détection détecte le rayonnement infrarouge d'au moins deux longueurs d'onde. Au moins chaque pixel (100) de détection comprend au moins deux piles (110, 120) de détection à puits quantiques différentes, lesquelles sont polarisées à une tension commune (T polarisation).
