• : apertureless scanning near-field optical microscopy; diffuse signal; nanosphere lithography; photomultiplier tube; plasmonic nanostructures; Introduction SNOM (scanning near-field optical microscopy) is an imaging technique based on an optical near-field probe for high spatial resolution [1][2]. A version of

• this technique is the apertureless scanning near-field optical microscopy (aSNOM), also known as scattering scanning near-field optical microscopy (s-SNOM). aSNOM has demonstrated tremendous potential for the study of nanostructures, as it combines the extreme sensitivity of surface enhanced optical

• its adiabatic limit, i.e., for waveguides with gradually (adiabatically) varying cross-section, for which reflection-free SPP propagation and efficient transformation are predicted [6]. This gives rise to a new class of probes in apertureless scanning near-field optical microscopy (SNOM) that focus

• illuminated AFM cantilever tip apex exposes strongly confined non-propagating electromagnetic fields that can serve as a coupling agent for single dye molecules. Thus, combining both techniques by means of apertureless scanning near-field optical microscopy (aSNOM) enables concurrent high resolution
