摘要：
We present the lasing dynamics of an electrically pumped quantum dot vertical-cavity surface-emitting lasers (QD-VCSELs) using self-consistently combined QD-WL Maxwell-Bloch equations. In order to determine the dephasing times of the system, Coulomb and electron-phonon scattering processes between the quantum dot (QD) states and the QD-embedding wetting layer (WL) states are microscopically calculated and implemented into the material equations. The QD-WL Maxwell-Bloch equations are used to study the characteristics of the switch-on dynamics which are crucial for high-speed optical systems. The carrier dynamics and the electric field propagation are evaluated using the finite-difference time-domain (FDTD) method within the full structure of QD-VCSELs.
