Abstract
An active structure in the semiconductor die of an amplifier or converter includes a plurality of stacked active layers with different compositions. The different compositions lead to a spectral offset between the respective gain bands of the layers which widens the gain band of the amplifier or the optical bandwidth of the converter. Applications include fiber optic telecommunication networks.
