It is shown theoretically that semiconductor optical amplifiers (SOAs) with type-II quantum-well active regions in SOAs will have up to 10 dB lower interchannel crosstalk at high (>2.5 Gb/s) data rates. That reduction is attained via the corresponding increase in saturation energy without any reduction in the efficiency.
