Near-field excitation and near-field detection of propagating surface plasmon polaritons (SPPs) on Au waveguide structures  

MultiProbe Apertured NSOM Plasmonic Charactarization

Near-field excitation and near-field detection of propagating surface plasmon polaritons on Au waveguide structures has been perfomed with Nanonics Multiview 4000 Dual Probe system

 Schematic of the MV4000 experimental setup for near-field excitation and near-field collection of SPP on gold waveguide structure (SEM shown inset)   AFM and NSOM 3D images of the Au Waveguide and the SPP distribution. The arrow shows the position of the illumination probe. The NSOM image shows exponential SPP decay with a propagation length of 550nm
