Plasmonic gratings and nano-particle arrays in a metal-insulator-metalstructures are fabricated on an erbium doped silicon nitride layer. Thismaterial system enables simple fabrication of the structure, since the activenitride layer can be directly grown on metal. Enhancement of collected emissionof up to 12 is observed on resonance, while broad off-resonant enhancement isalso present. The output polarization behavior of the gratings andnano-particle arrays is investigated and matched to plasmonic resonances, andthe behavior of coupled modes as a function of inter-particle distance is alsodiscussed.
