摘要：
The linear gain saturation effect is shown to be important in determining the dynamics of MQW DFB lasers. A more realistic logarithmic dependence of material gain on carrier density is assumed in a newly developed comprehensive MQW DFB laser model. It is found through simulation that because of the linear gain saturation, the interplay between modal gain and differential gain leads to an optimum kappa L for maximum small-signal modulation bandwidth in the lambda/4-shifted MQW DFB lasers.
