  • Abstract
    We present a theoretical study of the ambient refractive index sensing characteristics of Au-Ag surface gratings written on a planar waveguide. Exact coupled-mode-theory 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.
