Paper Abstract

We describe the design of a waveguide Fabry-Pérot optical sensor with high sensitivity to surface refractive index change. The optical thickness and field can be accommodated in a high-refractive-index waveguide, leading to a high sensitivity. Incorporating the resonance structure further enhances the sensitivity.
