Figure 4From: Guiding properties of asymmetric hybrid plasmonic waveguides on dielectric substratesPropagation length and normalized modal area of silica- and MgF 2 -based AHP waveguide versus height of mismatch. (a) Silica- and (b) MgF2-based AHP waveguide. The insets indicate electromagnetic energy density profiles of different heights of mismatch.Back to article page
