Neural stimulation with high spatial and temporal precision is desirable both for studying the
real-time dynamics of neural networks and for prospective clinical treatment of neurological …

We report a phenomenon of focusing a radially polarized beam from the visible range by a
silver film with no hole on the optical axis and double-sided concentric corrugations. The …

We study the polarization characteristics of light emission and collection in the near field by
the tips of a Dual-SNOM (two scanning near-field optical microscopes) setup. We find that …

Enhancement of sub-wavelength optical fields using sub-micron plasmonic probes has
found many applications in chemical, material, biological and medical sciences. The …

This paper addresses an important issue of light throughput of a metal–coated tapered tip for
scanning near–field microscope (SNOM). Corrugations of the interface between the fiber …

Nanofocusing properties of a tip in the form of a dielectric tapered fiber with metal
apertureless coating and dielectric nanocladding can be tuned within a wide spectral range …

We investigate the performance of a simple corrugated aperture scanning near-field optical
microscope (SNOM) probe with various cladding metals. The probes have only one …

Spatial resolution of the near-field scanning optical microscope (NSOM) as an effective tool
for high resolution optical measurements strongly depends on the aperture properties of the …

We discuss theoretically the concept of spatial resolution in near-field scanning optical
microscopy (NSOM) in light of a recent work [Opt. Express 17 (2009) 19969] which reported …

We develop a semi-analytical method for analyzing surface plasmon interferometry using
scanning-probe tips as SP launchers. We apply our approach to Young double-hole …
