Abstract: | A systematic analysis of the influence of the capture, inter-level relaxation and exciton dephasing time constants on the dynamic behavior of quantum dot Fabry-Perot semiconductor lasers is done taking into account the lasing from the ground and excited states. The simulation results show that the carrier time constants studied influence significantly the static characteristic of the laser, its switch-on response and the pulses generated by gain-switching. |
