Figure 4. Coupling between the plasmonic and BSW modes.

Figure 4

(a) White light image of the Ag NW and polymeric NW on the multilayer. The diameter of the polymer NW is about 170 nm and that of Ag NW is 90 nm. The location of the Ag and polymer nanowires are the darker lines. (b) FFP image of the light beam propagating along the two NWs with the incident wavelength at 630 nm.
