Research output: Contribution to journalConference articlepeer-review


The principal advantages of using short pulses for four-wave mixing (FWM) in semiconductor optical amplifiers are described. In a semiconductor optical amplifier, the efficiency of the FWM process is bound by gain saturation, and large CW optical fields are incapable of overcoming this bound. With short pulses on the other hand FWM is a dynamic process in which the gain is in a transient, making it possible to obtain large intensities in the presence of an unsaturated gain and achieve efficiency increases of several orders of magnitude compared to the CW case.
