Abstract
The invention provides an integrated optical waveguide sensor module (200) with reduced signal modulation and increased sensitivity. An optical waveguide sensor module (200) comprises an optically transparent substrate (210) having a first and a second interface and an optical waveguide film (220) disposed on the substrate (210) with the first interface (225) therebetween, wherein the film (220) comprises at least one grating pad (235) that is optically coupled therewith. The substrate (210) and the optical waveguide film (220) are configured to reduce parasitic interference within the substrate.
