Abstract


Loss compensation in long-range dielectric loaded surface plasmon polariton (LR-DLSPP) waveguides has been theoretically studied. Rare-earth-ion-doped potassium double tungstates have been proposed as gain materials because of the elevated gain that they can provide, together with a favorable refractive index. The effect of the waveguide geometry on loss compensation efficiency was thoroughly studied. A material gain as low as 12.5 dB/cm was found to suffice to achieve full loss compensation in an optimized structure.
