ABSTRACTWe report on the experimental observation of localized surface plasmons sustained by small metallic particles using a photon scanning tunneling microscope (PSTM). The surface plasmons are excited in gold nanostructures tailored by electron beam lithography. The constant height operation of the PSTM allowed a direct comparison with theoretical computations of the distribution of the optical near-field intensity. Plasmon coupling above a chain of Au particles and electromagnetic energy transfer from a resonantly excited nanoparticle to a nanowire are demonstrated. Our experimental results appear to be in good agreement with theoretical computations based on the Green's Dyadic Technique.

Tunneling Microscopy

Recent development of novel scanning probe techniques such as Scanning Tunneling Microscopy (STM), Atomic Force Microscopy (AFM), and Near-Field Optical Microscopy (NFOM) has opened new ways to study local field distribution of surface electromagnetic waves. A lot of experimental efforts have been concentrated on the study of surface plasmons (SP). Different techniques allow to excite and probe SPs with wavelengths from 1 nm down to the optical range along its entire dispersion curve. Large number of phenomena have been studied directly, such as SP scattering by individual defects, strong and weak localization of SP, SP induced local field enhancement, light emission from the tunneling junction, etc. Scanning probe techniques allow not only topography and field mapping but also surface modification and lithography on the nanometer scale. Combination of these features in the same experimental setup proved to be extremely useful in SP studies. For example, some prototype two dimensional optical elements able to control SP propagation have been demonstrated.

Plasmon Polaritons

We demonstrated the coupling of localized surface plasmons and surface plasmon polaritons modes in a system composed of a metallic particle chain separated from a thin metallic film. The results showed that: (1) the thickness of the metallic particles buried in the dielectric space, (2) the positions of the particles influence the level of interaction between localized surface plasmons and surface plasmon polaritons modes. Meanwhile, the positions of the particles and the thickness of the metallic particles control the electromagnetic enhancement and influence the electric field distributions in this system. This kind of system has a very promising candidate for biosensing and surface enhanced spectroscopy applications.
