The invention relates to an optical fiber comprising a gain medium which is equipped with: a core (22) which is formed from a transparent material and nanoparticles (24) comprising a doping element and at least one element for enhancing the use of said doping element; and an outer cladding (26) which surrounds the core. The invention is characterized in that the doping element is erbium (Er) and in that the enhancing element is selected from among antimony (Sb), bismuth (Bi) and a combination of antimony (Sb) and bismuth (Bi). According to the invention, one such fiber is characterized in that the size of the nanoparticles is variable and is between 1 and 500 nanometers inclusive, and preferably greater than 20 nm.
A method for manufacturing a preform intended to generate an optical fibre including a core made up of a transparent matrix and of nanoparticles that comprise a doping element and at least one element that enhances the use of said doping element, and further of an outer cladding surrounding the core, comprising:
