Centre for Nanostructured Media
University of Belfast,
University Road, Belfast BT7 1NN, U.K.
The project will be carried out at the Nano-optics and Near-field Spectroscopy Group at QUB.
Main research directions of the Group include scanning near-field
optical microscopy (SNOM), nano-spectroscopy and novel nanoscale
imaging techniques for material characterization, nonlinear nano-optics
and surface-plasmon nano-optics. Group research is funded by EPSRC (UK),
The Royal Society, EC FP6, industry and local government. Group
participates in FP6 NoEs Plasmo-Nano-devices and PHOREMOST:
Photonics to realize molecular scale technology.

Recent research achievements of the Group
include: - pioneering near-field studies of surface plasmon
polariton behaviour on rough and nanostructured surfaces, two-dimensional
surface polariton optics and optical properties of surface
polaritonic crystals; - development of scanning near-field
microscopy of second-harmonic generation, near-field second-harmonic
imaging of domain structures in ferromagnetic and ferroelectric
materials, development of apertureless second-harmonic scanning near-field
microscopy; - pioneering studies of nonlinear optical effects at low
light intensities mediated by localised surface plasmons and surface
plasmon polaritons in metallo-dielectric nanostructures for
applications in active elements of all-optical integrated circuits;
- development of a new concept of far-field optical microscopy with
the subwavelength resolution using surface plasmon polaritons.
