A: NSOM collection mode image shows light distribution from an array of 136nm holes and spaces in gold. Illumination is from below with NSOM collection from above the aperture array. Arrow indicates polarization of the incident light with plasmonic propagation at 900 to the polarization. This demonstrates extraordinary transmission (EOT).
B: 3D Collage of the above NSOM image correlated with AFM topography. The distribution of light is more intense at the higher metal lines than in the apertures.
