Abstract :
This paper measures sub-10 ps dynamics and magnitudes of gain and phase changes in InAs/GaAs quantum dots semiconductor optical amplifiers (SOA), Also this paper investigates the devices´ suitability for different signal processing schemes. It is found that the pump-induced gain saturation dominates over nonlinear phase shifts, and is is inferred that QD SOAs are especially useful in signal processing schemes that exploit gain effects only.
