Abstract
An amplifier optical fiber comprising a central core of a dielectric matrix doped with at least one element ensuring the amplification of an optical signal transmitted in the fiber and a cladding surrounding the central core and suitable for confining the optical signal transmitted in the core. The fiber also comprises metallic nanostructures suitable for generating an electronic surface resonance in the dielectric matrix of central core, the wavelength of said electronic surface resonance corresponding to an excitation level of the element ensuring the amplification.
