Abstract

Summary form only given. Ultrafast gain dynamics in semiconductor optical amplifiers (SOAs) has recently received considerable interest because of the potential application of SOAs in high-speed optical networks. It also provides a better understanding of the fundamental physical processes involved in the interaction between a short optical pulse and a high density plasma. We have performed cross-gain modulation experiments with 120 fs time resolution on a 600 ym long SOA. A weak cw probe beam is injected into the SOA, together with a strong pump pulse. The probe output signal is time-resolved by upconversion.
