Amplification of an optical pulse sequence in semiconductor optical amplifiers

The semiconductor optical amplifiers (SOA) are a base component in the fiber-optic transmission lines. We investigate the interaction with optical pulses of the Traveling Wave (TW) SOA having a typical parameters originated from a semi-classical model of two-level systems. An application of TW SOA as in-line amplifier for an optical pulses sequence and received "pattern" effect is shown.
