Side-hole fiber sensor based on surface plasmon resonance
Abstract
Surface plasmon resonance (SPR) is demonstrated in a microstructured optical fiber sensor for the first time (to our knowledge). SPR features were observed at 560 and 620 nm when sample fluids of refractive indices n=1.38 and n=1.41, respectively, were applied to the sensor. This study also identifies a new approach to improve the resolution of fiber SPR sensors.
