The dynamics of quantum dot semiconductor amplifiers are investigated theoretically with respect to the potential for ultrafast signal processing. The high-speed signal processing capacity of these devices is found to be limited by the wetting layer dynamics in case of electrical pumping, while optical pumping partly removes this limitation. Also, the possibility of using spectral hole burning for signal processing is discussed.
