Dynamic measurement of an angular Goos-Hänchen shift at a surface plasmon resonance in liquid

We developed a surface plasmon resonance (SPR)-enhanced angular Goos–Hänchen (GH) shift measurement system capable of tracking small refractive index changes with high sensitivity in a liquid environment. Our method can be performed in angular interrogation schemes, where we demonstrate a simple zero-finding algorithm to locate the SPR angle instead of the complicated data processing algorithms used in conventional sensors.
