We demonstrate that broadband characteristics of the responsivity depend much on the geometrical parameters of the detectors. %G English %L hal-01336498 %U https://hal.science/hal-01336498 %~ CNRS %~ UNIV-VALENCIENNES %~ IEMN %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ UNIV-LILLE %~ UM-2015-2021 %~ TEST3-HALCNRS
