High-performance portable grating-based surface plasmon resonance sensor using a tunable laser at normal incidence

Photonics Research, Journal Year: 2024, Volume and Issue: 12(5), P. 947 - 947

Published: March 1, 2024

Surface plasmon resonance (SPR) sensors are among the most sensitive sensors. In such devices, a grating is compelling alternative to prism for excitation of surface plasmon, especially in development point-of-care applications due their compactness and cost-effectiveness. Here, we demonstrate use tunable laser grating-based SPR system further miniaturization integration. The working at normal incidence replaces spectral moving components, while also simplifying optical setup. Normal conventionally avoided complexity control degenerated modes. We investigate, both computationally experimentally, splitting modes small nonzero incidences, which lacking previously reported studies. By optimizing configuration, were able diminish mode phenomenon when was feasible with configuration. fabricated sensor showed high sensitivity 1101.6 nm/RIU. Notably, figure merit sensor, defined as ratio between bandwidth dip, 229.5. experimental results consistent simulation results. its capability detecting low concentrations glucose creatinine limit detection 14.2 19.1 mmol/L, respectively.
