Ultra-sensitive long-range surface plasmon modes in asymmetric double-electrode waveguide

We present a theoretical study on an index-asymmetric double-electrode waveguide structure and identify a long-range surface plasmon polariton (LRSPP) super-mode for index-sensing. We propose to operate the LRSPP by monitoring its cut-off wavelength which promises ultra-sensitivity. The sensitivity...
