Abstract
A prism coupler based plasmonic sensor consisting of a prism, gold (Au) metal film and dielectric sample has been investigated with the use of admittance loci method in wavelength interrogation mode. Prism materials namely fused silica, chalcogenide (2S2G) and silicon have been used to study their effect on surface plasmon sensing in wavelength interrogation mode by admittance loci plots and by corresponding surface plasmon sensing curves. The performance of the plasmonic sensor under wavelength interrogation mode based on the choice of the prism material has been discussed and validated by the dynamic range and sensitivity plots.
