    摘要: A stimulated Raman effect (SRS) amplifying optical fibre comprising a core made up of a dielectric matrix capable of vibrating at a given frequency (ω Raman ) under the effect of a pump signal. The optical fibre comprises at least one type of metallic nanostructures capable of generating surface plasmon resonance (SPR) in the optical fibre, the metallic nanostructures having a shape and composition such that the frequency of their surface plasmon resonance (ω plasmon ) corresponds to the frequency of the pump signal (ω pump ) and/or the frequency of the optical signal transmitted in the optical fibre (ω signal ). At least one of the dimensions of the metallic nanostructures is comprised between 1 nm (nanometer) and 20 nm (nanometer) and the total volume of the metallic nanostructures is less than 2% of the total volume of the core of the optical fibre.
    The fibre has an increased Raman Figure of Merit (FOM).
