摘要：This optical device (100) for a biological or chemical sensor comprises an absorption cavity (110) intended to receive a biological or chemical medium; an injection waveguide (120) for injecting an analysis light beam (150) into the absorption cavity; and an extraction waveguide (130) for extracting a measurement light beam (160), corresponding to the analysis light beam after transit through the absorption cavity. The absorption cavity has a right-cylindrical shape with a base the shape of an elliptical segment. One end (121) of the injection waveguide is placed at a first focus (F1) of the ellipse and one and (131) of the extraction waveguide is placed at a second focus (F2) of the ellipse. The core of the injection waveguide (120) and the core of the extraction waveguide (130) each have a tip-shaped end, with a constant height in a plane parallel to the generatrix of the right cylinder and a tip-shaped cross section in planes parallel to the base of the right cylinder.
