Abstract
An optical sensing system is provided, including a sensing module, a light emitter, and a light receiver. The sensing module has a substrate, an optical waveguide disposed on the substrate, and a sensing membrane disposed on the optical waveguide for carrying a specimen. The light emitter emits a sensing light to the optical waveguide, and the light receiver receives the sensing light that propagates through the optical waveguide.
