  • Publication number: 20130102066
    Abstract: The invention relates to a fibre sensor that enables the propagation of infrared light at at least one wavelength of 0.8 to 25 micrometres, the fibre successively comprising along its length a first infrared waveguide section (23), a second detection section (25) intended to come into contact with an external environment in order to detect infrared signatures interfering with the propagation of the evanescent waves propagating along the fibre (2), and a third infrared waveguide section (27). The invention is characterized in that, in the second fibre section (25) that has the detection role, the fibre (2) is constituted of a curved part, the radios of curvature of which is locally less than 2.3 millimetres.

  • Publication number: 20060016224
    Abstract: The invention concerns a reaction chamber comprising a first container (1), a second container (4) connected to a conduit (6), an outer tube (3) emerging into the container (1), an outer tube (8) emerging into the conduit. The container (1) is designed to receive a sleeve glass, and the container (4) a core glass for optical fiber. The method for using said chamber, after vacuum sealing in (3a) and (8a), and heating the chamber at a sufficient temperature for melting the glasses, the chamber being in the position represented with the tube (3) in vertical position, consists: in a 180° anti-clockwise rotation about an axis perpendicular to the figure. The sleeve glass flows into the tube (3) while the core glass remains confined in the container (4); cooling the tube (3), then returning to the original position; part of the sleeve glass, maintained in liquid form in the center of the tube (3), drops into the container (1); carrying out another 180°, rotation, but clockwise.
