Abstract :
The line shape and noise characteristics of narrow linewidth MQW DFB lasers were measured in the range near the linewidth rebroadening. Excellent correlation between the linewidth rebroadening and line shape change was observed. The linewidth rebroadening is also related to the intensity and frequency noise characteristics.<>
