Abstract

We discuss the nonorthogonality of the longitudinal modes of the distributed feedback (DFB) lasers. The excess-noise factors in real DFB structure with end reflectivity are shown. Moreover, the effect of complex coupling coefficient on the excess-noise factor in partly gain coupled DFB lasers is analyzed.
