    SPR-based infrared detection of aqueous and gaseous media with silicon substrate
    (2009) Jha; R. and Sharma; A. K.
    A high-accuracy surface plasmon resonance (SPR) sensor with silicon substrate and Al-Au bimetal is proposed for aqueous and gaseous detection in infrared (IR) with a single probe. Angular interrogation method is used for SPR excitation using infrared source in the Kretschmann-Reather configuration. Sensor's performance is analyzed in terms of intrinsic sensitivity (IS) that includes the width and shift of SPR curve for given refractive index of sensing medium. In a broadband IR range of 1200 nm (700 nm-1900 nm)
