Abstract:
The interaction of light with metal surfaces has inspired people for centuries. Most people are familiar with examples of stained-glass windows and colourful goblets that create dramatic effects by incorporating small metallic particles in the glass.
Research activity on the coupling of electromagnetic light with electron oscillations in a metal (surface plasmon polaritons) has grown steadily since the 1950’s. With the increased availability of nanoscale fabrication techniques in the 1990’s the field saw a resurgence of activity which continues today.
Surface plasmon polaritions propagate along metal–dielectric interfaces and can be guided by metallic nanostructures beyond the diffraction limit. This remarkable characteristic has led to developments in the design of integrated photonic signal-processing systems, high resolution optical imaging techniques and sensors. One of the best known and commercially most successful application of plasmonics is in bench-top surface plasmon resonance (SPR) biosensor systems.
This talk will discuss work to develop a miniaturized sensor platform using long range surface plasmon polaritions (LRSPP) propagating at the surface of thin metal strips. Design of a hydrogen sensor using this technology will be described.
