Abstract
"Palladium films show a complex refractive index change when exposed to hydrogen. This refractive index change is reversible and can be used as a mechanism for sensing trace amounts of hydrogen gas. Here we propose a design for an optical hydrogen sensor by incorporating a thin palladium film into an optical waveguide. This waveguide will be ""carved out"" of a photonic crystal slab: a two-dimensionally periodic structure that can be engineered to guide light and can be fabricated using current planar technology."
