Study of an evanescent optical integrated sensor in the Mid-IR. Optimization of the ridge waveguide design to obtain the highest sensitivity in the Mid-IR. A numerical example is included using a chalcogenide ridge waveguide. Limits of detections of ppb are achieved for liquids and gases in the Mid-IR.
