Abstract | Full Text

Surface plasmon resonance (SPR) based fiber optic sensor with three types of bilayer configurations (silver/gold, copper/gold, and aluminum/gold) is theoretically analyzed. Performance parameters like sensitivity, signal to noise ratio, figure of merit, and resolution are evaluated for each configuration. Signal to noise ratio (SNR), and figure of merit (FOM) are enhanced very well for the selected bilayer configurations as the outer gold layer thickness increased, the sensitivity enhanced also but with small frictions while the resolution has decreased slightly.
