The influence of the gain saturation of the active medium and system parameters such as loss coefficient, coupling coefficient, and waveguide geometry on the 3 dB modulation bandwidth in fiber distributed feedback lasers is discussed for various transverse laser modes. Additionally, the effect of the amplitude and phase of the end reflectivity is taken into account. The characteristics revealing competition between the Fabry-Perot resonator and the distributed feedback resonator are presented.
