摘要：

Using the Bloch-wave analysis, this paper investigates the effect of the gain grating on the single-mode condition in DFB lasers, Various factors affecting the threshold gain of gain-coupled DFB lasers are analyzed in some detail, It is shown for the first time that unequal section lengths in the gain grating can have a significant effect on the single-mode gain margin of gain-coupled DFB lasers, especially when the linewidth enhancement factor alpha(M) is large, because the long and short wavelength Bloch waves are in phase and in antiphase with the index grating of DFB lasers, respectively.
