Claim 0:
1. An optical amplifier, comprising:
an optical signal divider having an input and a plurality of outputs, wherein the optical signal divider is operable to receive an optical signal having a first bandwidth and divide the optical signal into subbands for distribution among the plurality of optical signal divider outputs;
a plurality of semiconductor optical amplifiers, wherein each semiconductor optical amplifier of the plurality of semiconductor optical amplifiers:
has an input coupled to a respective optical signal divider output of the plurality of optical signal divider outputs,
is tuned to amplify a respective subband within the first bandwidth of the optical signal, and
has an output to output an amplified optical signal encompassing the respective subband; and

an optical signal combiner coupled to the output of each of the plurality of semiconductor optical amplifiers, wherein the optical signal combiner is operable to combine each respective amplified optical signal encompassing the respective subband, and output an amplified optical signal having the first bandwidth.
