Abstract
An amplifying optical fiber includes a core containing Tm ions as activation ions and a clad containing at least one of Tb ions and Eu ions. Alternatively, the amplifying optical fiber includes a core composed of more than two layers. Tm is contained in more than one of the more than two layers as activation ions and at least one of Tb ions and Eu ions is contained in more than one of the more than two in which Tm is not contained.
