      LabH6: Passive optical fibers for nuclear instrumentation

      Many high energy physics facilities, the nuclear or dismantling industries require single-mode or multi-mode optical fibers operating in the infrared domain, most often at Telecom wavelengths: 1310 nm and 1550 nm. These optical fibers are used for data transfer or serve as sensitive elements to distributed sensors of temperature, strain, liquid levels...

      LabH6: Optical fibers, optical amplifiers and fiber lasers

      Rare earth ion doped fibers (Er3+, Yb3+ or Er/Yb) are crucial elements in the design of optical amplifiers or fiber lasers. These components are then used in more complex systems such as fiber optic gyroscopes or high-speed free-space optical communications. Radiation tests show that commercial active optical fibers, components and associated systems are highly vulnerable to space radiations.

      LabH6: Optical fibers for distributed ionizing dose measurement

      Studies are being conducted in close collaboration with CERN to define and qualify a distributed dosimetry solution. By combining a radio-sensitive fiber with an optical reflectometer, the dose can be measured along a fiber with a sub-metric resolution.

      LabH6: “Canonic” optical fibers for fundamental studies

      To become able to control the radiation response of optical fibers, it is necessary to identify the nature, the optical properties, the generation and bleaching mechanisms of these defects. The ultimate goal of these fundamental studies is to predict, through simulation, the response of an optical fiber for a given application and specific environment.

      LabH6: “New specialty optical fibers

      Different applications require the development of dedicated optical fibers. Those fibers must then have their optical properties optimized for the intended application, obtained by working on their refractive index profiles and/or compositions.

      CERTYF : PIA project

      CERTYF is a fundamental research project with the aim of improving the understanding of the basic mechanisms governing the degradation of optical fibres (loss of some optical properties via a radiation-induced attenuation phenomenon) in complex environments combining the following stresses: temperature, radiation and hydrogen.

      SURFIN : PIA project

      SURFIN aims to characterize new luminescent vitreous materials, based on doped silica (intentional implantation of some elements to modify the properties of optical fibers), and to implement them in fiber solutions for in situ dosimetry of different radiation environments (X, γ, …).
