Excitation of surface plasmons on metallic nanoparticles has potential for increasing the absorption and emission from thin Si devices. We report an eight-fold enhancement in electroluminescence from silicon-on-insulator light-emitting diodes at via excitation of surface plasmon resonance in silver nanoparticles, along with a redshift in the electroluminescence by by overcoating the nanoparticles with . The enhancement is due to coupling between the electromagnetic excitations of the silver nanoparticles and the waveguide modes.
