  • Rare-earth-doped amplifying optical fiber
    Patent number: 9162917
    Abstract: An amplifying optical fiber includes an inner core, an inner cladding, a depressed trench, and an outer cladding (e.g., an outer optical cladding). Typically, the inner core includes a main matrix (e.g., silica-based) doped with at least one rare earth element. The depressed trench typically has a volume integral V13 of between about ?2200×10?3 ?m2 and ?1600×10?3 ?m2. Exemplary embodiments of the amplifying optical fiber are suitable for use in a compact configuration and high power applications.

  • DEUTERIUM TREATMENT METHOD FOR OPTICAL FIBRES
    Publication number: 20100251775
    Abstract: A treatment method for an optical fibre including the steps of exposing the fibre to an atmosphere containing deuterium at a given temperature, concentration and pressure, measuring the attenuation in the fibre as a function of time at least one wavelength, during the exposure of the fibre to an atmosphere containing deuterium, identifying an attenuation maximum after an exposure duration, and stopping the exposure of the fibre to the atmosphere containing deuterium when said duration has elapsed.
