Abstract: An optical fiber comprising a core region doped with a first alkali dopant and a second alkali dopant. The first alkali dopant has a first average core concentration of C1 and a first diffusivity D1. The second alkali dopant has a second average core concentration of C2 and a second diffusivity D2. An outer cladding region surrounds the core region. The diffusivities D1, D2 of the first and second alkali dopants satisfy the relation D1>D2. The average core concentrations C1, C2 of the first and second alkali dopants satisfy the relation 0.1≤C2/C1≤1.
