摘要
The emission of erbium ions in silica glass around 1.55 mu m is significant enhanced by the surface plasmon polaritons (SPPs). The coupling efficiency between the SPPs and the photons is calculated by the rigorous coupled-wave analysis. The external quantum efficiency (EQE) of the erbium-doped silica materials assisted by using the double metallic grating (DMG) could increase 2.45 times than that by using the single metallic grating (SMG).
