Abstract:
1. A broadband optical amplifier comprising: an input having a plurality of optical wavelengths, including optical wavelengths between 1610 and 1620 nanometers; a first optical splitter optically connected to the input, the first optical splitter splitting the input into at least a first band signal portion and a second band signal, wherein the first optical splitter comprises the first optical splitter adapted to split the input broadband portion into the first band signal portion and an intermediate signal portion and a second optical splitter adapted to split the intermediate portion into the second band signal portion and a third band signal portion; an amplifying portion optically disposed along each of the at least first and second band signal portions optically downstream from the first optical splitter; and a first optical combiner optically connected to the at least first and second band signal portions to form an output.
