Subwavelength optical waveguides coated with porous silsesquioxane‐palladium nanocomposites are used to detect hydrogen gas. This compact waveguide sensing platform shows extremely fast response times over short interaction lengths and can be reused by stripping/re‐depositing the chemo‐responsive nanoparticle coatings.
