Optical fibre nanowires and microwires offer a variety of enabling properties, including large
evanescent fields, flexibility, configurability, high confinement, robustness and compactness …

We present a detailed Mie theory, finite-difference time-domain, and quasi-static study of
plasmon–exciton interactions in a spherical core–shell geometry. In particular, we report …

Nearfield scanning optical microscopy (NSOM) offers a practical means of optical imaging,
optical sensing, and nanolithography at a resolution below the diffraction limit of the light …

Techniques to resolve images beyond the diffraction limit of light with a large field of view
(FOV) are necessary to foster progress in various fields such as cell and molecular biology …

Near-field optics and superlenses for imaging beyond Abbe's diffraction limit are reviewed. A
comprehensive and contemporary background is given on scanning near-field microscopy …

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 theoretically demonstrate the possibility of obtaining nanosources through an original
schema based on the generation of the radially polarized surface plasmon mode of a …

We propose a technique of chemical etching for fabrication of near perfect optical fiber
nanoprobe (NNP). It uses photosensitive single mode optical fiber to etch in hydro fluoric …

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 …

A near-field antenna array probe is presented that can perform subwavelength-focused
imaging at a distance of 0.25¿. The array is composed of a centrally fed dipole with open …
