Devices (100) and techniques for coupling radiation to intraband quantum well semiconductor sensors that are insensitive to the wavelength of the coupled radiation. At least one reflective surface (150,152) is implemented in the quantum well region (130) to direct incident radiation towards the quantum well layers.

La présente invention concerne des dispositifs (100) et des techniques de couplage de rayonnement pour des capteurs semi-conducteurs intrabandes à puits quantiques qui sont insensibles à la longueur d'onde du rayonnement couplé. Au moins une surface de réflexion (150, 152) est mise en oeuvre dans la zone à puits quantique (130) pour diriger un rayonnement incident vers les couches du puits quantiques.
