摘要：

We would like to present here a geometry of Quantum Well Infrared Photodetectors (QWIPs) for increasing the detectivity. It consists of a mesa (a squared etched pixel) with a metal grating on top of it. The grating concentrates the electromagnetic field in the electric area defined by proton implantation. We focus on the design of the grating based on Floquet Bloch S-Matrix calculations. For the optimisation, the relation between the electronic structure of the detector and the pixel geometry is highlighted.
