Abstract

The effect 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 planar and fiber waveguide distributed feedback lasers is discussed for various transverse laser modes. Additionally, the influence of the amplitude and phase of the end reflectivity on the modulation bandwidth is analyzed for both structures. Moreover, the spatial hole burning effect on the modulation bandwidth f_{3 dB} for the various system parameters is investigated. It is shown, that in general, the spatial hole burning effect increases the 3-dB modulation bandwidth in both structures
