    摘要： Disclosed is a stimulated Raman scattering effect (SRS), amplifying optical fiber that includes a central core comprising a dielectric matrix that is capable of vibrating at a given frequency (ωRaman) under the effect of a pump signal. The optical fiber includes at least one kind of metallic nanostructure that is capable of generating surface plasmon resonance (SPR) in the optical fiber. The metallic nanostructures have a shape and composition such that the frequency of their surface plasmon resonance (ωplasmon) corresponds to the frequency of the pump signal (ωpump) and/or the frequency of the optical signal transmitted in the optical fiber (ωsignal).

    摘要： An optical fiber includes a central core and an optical cladding. The central core includes a core matrix surrounding nanoparticles. The nanoparticles include rare earths, a nanoparticle matrix, and an outer layer. The nanoparticle matrix surrounds the rare earths, and the outer layer surrounds the nanoparticle matrix. The atomic ratio of nanoparticle matrix atoms other than oxygen to rare earth atoms is typically between about 300 and 1,000. The outer layer, which typically has a thickness of between about 1 nanometer and 2 nanometers, includes an outer layer matrix that is substantially free from rare earths.

    摘要： The invention relates to a method for manufacturing a final optical fiber preform by overcladding, said method comprising the steps of providing a primary preform; positioning said primary preform within at least one tube, wherein the at least one tube partly covers the primary preform to create a zone to be overcladded, being an overclad zone, which overclad zone is located on the primary preform outside the at least one tube; injecting a gas into the annular space between the primary preform and the at least one tube under overpressure relative to the pressure outside the at least one tube; overcladding the primary preform in the overclad zone with an overcladding material using an overcladding device. The invention also relates to an apparatus for carrying out the method. The invention allows overcladding a primary preform at low cost while maximally limiting the incorporation of impurities into the silica overclad.

    摘要： A method for producing an optical fiber preform (100) consists in producing a primary preform (110); drawing out an end portion (115) of the primary preform (110) to produce a tail portion (115); thickening (120) the primary preform; and forming a cone (130) on the drawn out tail portion at the end of the primary preform. As a result of drawing out an end portion of the primary preform, the amount of primary preform required for cone formation is reduced while simultaneously optimizing cone length and angle appropriate to good initiation of fiber drawing.

    摘要： Disclosed is an amplifying optical fiber that includes a central core that is suitable for transmitting and amplifying an optical signal and a surrounding optical cladding that is suitable for confining the optical signal transmitted in the central core. The central core is formed from a main matrix that contains nanoparticles doped with at least one rare earth element. The weight concentration of the rare earth dopants in the nanoparticles is typically between about 1 and 20 percent, and the nanoparticle concentration in the central core's main matrix is between about 0.05 percent and 1 percent by volume. The disclosed optical fiber incorporates rare earth ions at high concentrations yet avoids the phenomenon of photodarkening at high transmission power.

    摘要： A method for manufacturing a final optical fiber preform via overcladding of a primary preform having a cross section area is disclosed. The method includes at least one manufacturing step of the primary preform by deposit of an inner cladding and of a central core inside a tube of fluorine-doped silica, the tube being chosen such that it has a cross section area that is maximally about 15% less than the cross section area of the primary preform. With the method of the invention it is possible to manufacture a preform of large capacity at reduced cost which allows the drawing of an optical fiber having reduced transmission losses.
