摘要： The amplifying optical fiber comprises a single-mode core and a multimode core surrounding the single-mode core, the multimode core containing a doped layer referred to as a “doped ring” and having a certain concentration of active rare earth ions to perform amplification by active rare earth ions on at least one optical signal for injection into the amplifying fiber. The fiber is dimensioned so that the product of its length multiplied by its Raman efficiency is greater than or equal to 0.5 W−1. In addition, the fiber presents absorption defined by an absorption coefficient expressed in dB/m, which absorption presents, at a certain wavelength, a maximum value referred to as the “absorption maximum”, the fiber presents accumulated absorption, corresponding to the product of its length multiplied by the absorption maximum, that is greater than or equal to 100 dB. The invention also provides an amplifier including such a fiber, a single-mode pump, and a multimode pump.

摘要： An optical fiber has a fiber core with a higher refractive index and a cladding surrounding the core with a lower refractive index. The fiber core is made of a multi-component oxide glass composition which consists of a glass-forming component and two Raman-active components. The glass former is SiO2 and the Raman active components are of Li2O and Nb2O5. The concentration of the glass former is between 30 and 90 mol % and of the Raman active components is up to 50 mol % in total. The composition may further include a glass-modifying component of alkaline such as Li2O, Na2O, K2O, Rb2O, Cs2O or earth-alkaline such as BeO, MgO, CaO, SrO, BaO in a concentration of up to 40 mol %.
