Abstract

The chemical sensing device comprises a substrate of semiconductor material, integrated circuit components and a photodetector formed in the substrate, a dielectric on the substrate, a wiring in the dielectric, and a source of electromagnetic radiation, a waveguide and a fluorescent sensor layer arranged in or above the dielectric. A portion of the waveguide is arranged to allow the electromagnetic radiation emitted by the source of electromagnetic radiation to be coupled into the waveguide. A further portion of the waveguide is arranged between the photodetector and the fluorescent sensor layer.
