NanoPumpProbe Optical Measurements

 Apertured NSOM probe is used to launch a 532nm laser on gold strip for near-field plasmons excitation (shown in topography image at left) and zoomed in the middle image. The right image is an NSOM collection mode obtained with a second probe shows plasmons propagation on the gold strip.Multiview 4000TM system allows for multiprobe scan probe microscopy protocols for effective localized illumination of plasmonic structure with an apertured NSOM probe which produces all k-vectors and so it is most efficient for such plasmonic propagation. The propagating plasmons are collected with a second probe which has a very low dielectric constant and minimal perturbation of the plasmonic propagation.
