Abstract

We show that erbium ions placed in an annulus within the fiber core make 980-nm-pumped amplifiers insensitive to variations in pump power distribution among the spatial modes of the fiber and make 1480-nm-pumped amplifiers insensitive to variations in fiber parameters. © 1993 Optical Society of America.
