Abstract: (4230 Views)
In this paper, a passively quantum dot mode-locked laser (QD-MLL) has been analyzed based on the rigorous numerical model. The structure is a Fabry-Perot laser consisting of a reverse-biased saturable absorber and a forward-biased amplifying section. In order to describe the dynamic behavior of the laser, we use traveling wave equations coupled to quantum dot rate equations. Also, we investigate the effect of negative voltage applied to the absorber section on the mode locking performance of the laser. Results show that by increasing the negative voltage applied to the saturable absorber, the output pulse duration is decreased and output power is increased.
Keywords: Finite difference traveling wave, passively quantum dot mode-locked laser, saturable absorber
