    摘要: A sensing device for sensing a substance includes a photonics integrated circuit having a resonator element that supports two different radiation modes, e.g. radiation modes of different polarisation, at a predetermined resonance wavelength. The resonator element is configured to convert a phase change or amplitude change experienced by the two different radiation modes upon formation of a layer of receptor molecules onto a sensing surface of the device into a resonance wavelength shift for the two different radiation modes. The sensing device also includes a detection unit arranged to detect the resonance wavelength shift for the two different radiation modes. The detection unit includes a processor that is configured to derive from the detected resonance wavelength shifts for the two different radiation modes, a layer thickness and refractive index of the layer of receptor molecules.

    摘要: A photonic integrated circuit (410) is described comprising at least one signal processing circuit (110). The signal processing circuit (110) comprises at least one input coupling element (120) for coupling incident light from a predetermined incoupling direction into the photonic integrated circuit (410), and at least one output coupling element (130) for coupling light out of the photonic integrated circuit (410) into an outcoupling direction. The relation between the incoupling direction and the outcoupling direction is different from a relation according to the law of reflection and the incoupling direction and the outcoupling direction are substantially the same. Furthermore, an optical sensor probe (400) comprising such a photonic integrated circuit (410) is disclosed. In some embodiments, the optical sensor probe (400) comprises an optical fiber (420) having a first facet and comprises a sensing element physically attached to the first facet, wherein the sensing element comprises said photonic integrated circuit (410).
