Abstract

We have evidenced co- and counter-propagating dark pulses in the laser mode of gain clamped semiconductor optical amplifiers (GCSOA)s perturbed by an intense ultrafast pulse. They decay into a long-lived two mode beating. The resulting gain modulation may be a limiting factor for applications.
