Numerical mode analysis of nanoribbons. a Dispersions of nanoribbons by numerical modelling. The numerical results (symbols) were compared to the analytical results of light line, single interface and a thin film. b Zoomed-in plots of (a). The insets represent the electric field intensity distributions in the cross-section of a 5-µm wide nanoribbon at the four colour-filled symbols. c Propagating lengths of nanoribbons with 5 and 10 µm widths, corresponding to the dispersion in (a, b)
