Abstract

We report low-loss silicide/silicon plasmonic ribbon waveguides for mid- and far-IR applications. The composite modes in silicide ribbon waveguides offer a low-loss and highly confined mode profile, giving excellent plasmon waveguiding for long-wavelength applications. The calculated propagation loss of the composite long-range surface-plasmon polariton mode at a wavelength of 100 μ m is 2.18 dB/cm with a mode height of less than 30 μ m . The results presented provide important design guidelines for silicide/Si plasmon waveguides.
