Abstract
The disclosed invention includes an amplifier fiber and methods of making the amplifier fiber. One embodiment of the inventive fiber includes a glass core and a glass cladding layer surrounding the glass core. The cladding glass layer has a refractive index which is less than a refractive index of the glass core. The fiber also includes a glass overclad layer surrounding the cladding layer. The overclad layer has a refractive index which is greater than the refractive index of the cladding layer. In another embodiment of the inventive fiber, the overclad layer is doped with an absorber. The absorber strips a mode of light propagating in the cladding from the cladding layer.
