Telecommunication systems using 200 fs optical pulses for ultrahigh bit-rate optical transmission require new concepts to be developed for ultrafast all-optical switching. On the basis of numerical experiments, we discuss how a semiconductor optical amplifier in a Sagnac interferometric arrangement can be used for switching these short pulses. The switching principle is based on gain and index saturation dynamics on a sub-picosecond timescale. The model accounts for bi-directional propagation of ultrashort optical pulses through the amplifier as well as free-carrier absorption and two-photon absorption.
