Abstract :
We used the Lüdge-Schöll (LS) model of the optically injected quantum dot (QD) in a well (QDWELL) laser and carried out the numerical simulations for the LS rate equation system. We have shown that due to the optical injection, the electron and hole dynamics in QDs is synhcronized, the modulation frequency is enhanced, and the QDWELL laser manifests a high performance at the repetition frequency of 20 Hz, drastically deteriorating at 30 GHz .
