Waveguide modes.

(a–h) Logarithmic intensity distributions and polarizations indicated by white arrows. (a) The TE mode in the dielectric waveguide, (b) the corresponding TM mode, (c) the fundamental and (d) 2nd SPP mode of a simple stripe waveguide, (e,f) the corresponding modes of a slotted stripe waveguide, (g) the 3rd mode for this cross-section, i.e., the slot-stripe mode and (h) the sole and highly localized plasmonic slot-mode featuring a polarization allowing for excitation by the TE mode of the dielectric waveguide. All subfigures have separate color-gradients.
