Abstract
A broadband optical amplifier is disclosed. The amplifier includes an input having a plurality of optical wavelengths, including optical wavelengths between 1610 and 1620 nanometers, and a first optical splitter optically connected to the input. The first optical splitter splits the input into a first band signal portion, a second band signal portion, and a third band signal portion. An amplifying portion is optically disposed along each of the first, second, and third band signal portions optically downstream from the first optical splitter. A first optical combiner is optically connected to the first, second, and third band signal portions to form an output. A method of amplifying a broadband optical signal is also disclosed.
