Refractive Index Sensing Characteristics of Alternate Au–Ag Surface Gratings on Optical Waveguides
We present a theoretical study of the ambient refractive index sensing characteristics of Au-Ag surface gratings written on a planar waveguide. Exact coupled-modetheory has been used to consider the power coupling from guided mode to Surface-Plasmon- Polariton. A very high sensitivity ~1360 nm/RIU has been observed at metal thickness ~14 nm.
