Optical injection influence on quantum dot-in-a-well (QDWELL) laser dynamics
A QD laser with the dots-in-a-well structure (QDWELL laser) is characterized by the increased emission wavelength and low threshold current density. However, QDWELL laser manifests a high performance for the pulse repetition frequencies up to 7 GHz. The optical injection locking of semiconductor lasers substantially improves their performance. We, for the first time, investigated theoretically the influence of the optical injection on the QDWELL laser dynamics taking into account both the electron and the hole behavior in QW and in QDs. The results show that the maximum modulation frequency increases up to 30 GHz, the electron and hole dynamics is synchronized, and the oscillations occur at the strong injection level.
