Abstract :
An HgCdTe photoconductive infrared detector with metallic nanostructures has been numerically studied. The plasmonic resonant absorption and the photo current response spectra of the detector are investigated by using a combination of the FDTD method and FEM method. The simulated results show the dependence between the geometric design and the performance of the detector. A higher photo response can be achieved in comparison to common HgCdTe photoconductive infrared detector.
