| Abstract | ||
| The dynamics that occur in bulk semiconductor optical amplifier (SOA) like gain and phase dynamics in presence of pulses in subpicosecond and picosecond range are studied numerically. If the passing pulse through SOA in the femtosecond range, the ultrafast effects presented by the compression of gain, phase will appear and as a result, the recovery of them will be fast comparison with the pulse width in the picoseconds range which suffers from slow recovery. The dependence of the studied of the gain and phase on the pulse width was clear and the ultrafast effects present in this paper like spectral hole burning (SHB) and carrier heating (CH) and its effects on pulse chirp are studied extensively. | ||
