Abstract

We demonstrate the use of tilted fibre gratings to assist the generation of infrared surface plasmon resonances with short propagation lengths, resulting in a high index resolution of 2×10^-5 in the aqueous index regime. It was also found that the resonances could be spectrally tuned over 1000nm at the same spatial region with high coupling efficiency (in excess of 25dB) by altering the polarisation of the light illuminating the device.
