摘要

We propose a set of single mode rate equations for multi-section distributed feedback (DFB) lasers. On the basis of the rate equations, the self-pulsation in the two-section DFB lasers with asymmetrical injection current was explained.It was found that the dynamic distribution of the power in two sections play key role in the self-pulsation running.
