1 March 1995 Modulation bandwidth of dielectric waveguide distributed-feedback lasers
Author Affiliations +
The effects of the gain saturation of the active medium and spatial hole burning, and system parameters such as loss coefficient, coupling coefficient, and waveguide geometry on the 3-dB modulation bandwidth in planar and fiber distributed feedback lasers is discussed for various transverse laser modes. Additionally, the effect of the amplitude and phase of the end reflectivity on the modulation bandwidth is analyzed for both structures. The characteristics revealing competition between the Fabry-Perot resonator and the distributed feedback resonator are presented.
