Abstract

Quantum well detector, in which the active detection zone (2) occupies only a limited area of the device and in which a diffraction grid (5) having a larger surface area than this zone thereby makes it possible to couple to it a greater light flow than that corresponding to the surface area of this zone. In this way, the sensitivity of the device is increased. Application: Detection of optical radiation.
