Abstract

We demonstrate a bi-metal coating (platinum and gold or silver) localised surface plasmon resonance fibre device that produces an index spectral sensitivity of over 11,000 nm/RIU, yielding an index resolution of 5×10^-6in the aqueous index regime, consisting of a structured multi-layered thin film on D-shaped fibre.
