Abstract
Surface Plasmon Polariton (SPP) offers the opportunity to accelerate efficiently spontaneous emission of nanoemitters located close to a metallic surface, but as SPP modes are not coupled to far-field radiative modes, they induce loss of radiation. As metallic gratings radiate SPP modes in far field, they can be used to enhance the fluorescence of nanoemitters coupled to SPP. Moreover a periodically corrugated metallic surface offers the opportunity to absorb light with an efficiency close to 100% with applications in fields such as bio-imaging, light-emitting diodes (LED), photovoltaics or single-photon sources.
