International audienceIn photonics, the field concentration and enhancement have been major objectives for achieving sizereduction and device integration. Plasmonics offers resonant field confinement and enhancement, butultra-sharp optical resonances in all-dielectric multi-layer thin films are emerging as a powerful contestant.Thus, applications capitalizing upon stronger and sharper optical resonances and larger fieldenhancements could be faced with a choice for the superior platform. Here, we present a comparisonbetween plasmonic and dielectric multi-layer thin films for their resonance merits. We show that theremarkable characteristics of the resonance behavior of optimized dielectric multi-layers can outweighthose of their metallic counterpart
