  • Patent number: 11573365
    Abstract: A microstructured multicore optical fibre (MMOF) includes a cladding in which a plurality of basic cells are formed that run along the MMOF. Each of the basic cells includes a core, and at least one of the basic cells is surrounded by a plurality of longitudinal areas that run parallel to the core along the MMOF and are arranged in a hexagonal arrangement around the core. The longitudinal areas are spaced by a lattice constant ?. Sides of the hexagon can be shared with adjacent basic cells.

  • Patent number: 11493450
    Abstract: Disclosed is an interferometric fiber optic sensor for detecting chemical substances. A light source a detector are connected to a light dividing element in an optical path with an optical fiber segment. The optical fiber segment is further optically coupled with a measuring element across a residual cavity. The measuring element further has a face adapted to be exposed to a test substance that may contain a chemical substance to be detected. The optical fiber segment and the measuring element can be held together so that there is only the residual cavity between them. The optical fiber segment is contained, at least along part of its length, within a capillary. A first end part of the capillary is joined with the measuring element while another portion of the capillary is joined or clenched on the optical fiber segment, so that the capillary, the optical fiber segment and the measuring element together form a fiber optic measuring probe as a part of the optical path with the light source and detector.

  • Patent number: 11199656
    Abstract: Microstructured multicore optical fibre with a microstructure area, in which, at least two basic cells are embedded, where each of them contains a core, preferably made of glass, specifically including doped silica glass or polymer, together with the surrounding it longitudinal areas with lower refraction index vs. that of the cladding, which areas may adopt the shape of holes, filled with gas, in particular with the air or a fluid or a polymer or spaces of another glass with doping allowing to reduce refractive index (further referred to as holes), embedded in a matrix of glass, in particular of silica glass or polymer. The refraction index of the holes is decreased vs. that of the matrix of glass, in particular of silica glass or polymer. The basic cell is characterised by the diameter of D2 core, the diameter of D3 core and the distance between adjacent holes, corresponding to lattice constant A.

  • Patent number: 10866081
    Abstract: A waveguide interferometer includes a multicore fiber used a multicore waveguide, where the multicore waveguide includes a coupler section formed by tapering a portion of the multicore waveguide so that one core though which a light source is fed is optically coupled to another core that is terminated differently that the core into which the source signal is provided. The terminations respond differently upon being exposed to an environmental condition or substance, and the difference in response to the environmental condition or substance results in a shift in interference of the light reflected back through the multicore waveguide, which is detected with a detector on the same side of the multicore waveguide as the light source.
