The structure consists of excitingsurface plasmons through the illumination of a subwavelength hole in a silver film and in confiningthem at the vicinity of the aperture by surrounding the hole of Bragg mirrors resonant with theplasmons generated. Both finite element method computations and experimental results evidence theperformances of this device that could find applications, for example, in nanolithography or opticaldata storage. %G English %L hal-02329180 %U https://utt.hal.science/hal-02329180 %~ CEA %~ CNRS %~ UNIV-TROYES %~ DRT %~ LETI %~ CEA-GRE %~ UTT
