We report on recent progress made in the development of plasmonic nanolenses. These lenses exhibit intensity transmittance close to 80%, focal lengths equal to one or more wavelengths, and foci with full-widths at halfmaximum close to the diffraction limit. We consider lenses in the form of (i) a silver layer with no hole on the optical axis and double-sided concentric corrugations, (ii) a silver...
Scanning near-field optical microscopy (SNOM) is an important tool for measurements of nanostructures as well as chemical and biosensing applications. A key parameter defining its usefulness is its resolution which depends of the geometrical size of SNOM probes and signal throughput in aperture tips and signal enhancement in apertureless ones. We analyse nanofocusing properties of an apertureless...
