Opis:: We proposed a nano-imaging system at optical frequency region with the array of metallic nanorods. We simulated the field distribution of imaging process using the finitedifference time-domain algorithm. It is found that the spatial resolution is 40 nm, which is much beyond the diffraction-limit and is limited by the array pitch. The typical configuration is a hexagonal arrangement with 40 nm periodicity of silver rods of 50 nm height and 20 nm diameter. The image formation highly depends on the coherence and the polarization of the dipole sources, the array pitch, and the source-array distance. The principle of our near-field imaging is based on the longitudinal resonance of the localized surface plasmon along a metallic nanorod. The spectral responses of the device are also investigated.

Opis:: In the paper we experimentally and theoretically analyze diffraction of light propagating through a microstructured optical fiber on the fiber end face. In the measurements the diffracting light is spatially inhomogeneous and the diffracting object is a solid-state core with a triangular shape. Application of optical system enables detailed experimental investigations of evolution diffraction pattern in the near-field region, in particular, rotation of the observed structure while departing from the fiber end. The experimental results are confirmed with theoretical simulations based on the theory of the Fresnel diffraction.
