Hyperspectral imaging with scanning near-field optical microscopy: applications in plasmonics

Bouillard, J. S.; Vilain, S.; Dickson, W.; Zayats, A. V.

Abstract

We present the realisation of near-field spectroscopic measurements with fibre-tip-based scanning near-field microscopy. It allows the simultaneous acquisition of near-field images in a broad spectral range (400 nm to 1000 nm), thus recovering local spectroscopic information. This technique is essential in order to understand the resonant interaction of light with nanostructured material as the far-field and nearfield spectral response can differ significantly, e.g., in the case of plasmonic nanostructures. Several example applications of hyperspectral near-field imaging are given for visualisation of Bloch modes in plasmonic crystals and plasmon-assisted transmission through a slit. © 2010 Optical Society of America.
