Numerical simulation of a metal diffraction grating-based SPR sensor with a water-immersion lens

Numerical simulation of a metal diffraction grating-based SPR sensor with a water-immersion lens We describe a metal diffraction grating-based surface plasmon resonance sensor (G-SPRS) that operates in a differential mode, the angular sensitivity of which would be 4.8 times that of a conventional G-SPRS and over twice that of a prism-based SPRS. Because the objective is to analyze sample solutions using our G-SPRS, we plan to employ a water-immersion cylindrical lens to obtain simultaneously an angular spectrum of wide range.

Abstract

We describe a metal diffraction grating-based surface plasmon resonance sensor (G-SPRS) that operates in a differential mode, the angular sensitivity of which would be 4.8 times that of a conventional G-SPRS and over twice that of a prism-based SPRS. Because the objective is to analyze sample solutions using our G-SPRS, we plan to employ a water-immersion cylindrical lens to obtain simultaneously an angular spectrum of wide range. This G-SPRS enables us to observe two SPR dips corresponding to ±1st-order diffracted light in differential mode and further to generate them symmetrically at relatively large incident angles. We present simulation results and a practical optical design emphasizing its sensitivity in measurement, and thereby the significant advantage of its rigorous design.
