Abstract(in English) | Actively-modelocked external-cavity semiconductor lasers are good candidates for optical pulse sources used in optical communication systems because of their compactness. However, the pulse quality of such lasers is known to be strongly influenced by the carrier dynamics in the active layer. Since the carrier lifetime in semiconductor lasers is in the sub-ns region, the carrier density fluctuates in response to the pulse waveform. The carrier density fluctuation, in turn, causes the variation of the gain and the refractive index. We find a new mechanism originating from carrier density fluctuation which makes pulse trains unstable, and derive operation conditions for stable pulse generation. |
