The model is based on the traveling wave equations, which are solved by expanding the solution in terms of the longitudinal eigenmodes. It is shown that for a drastic enhancement of the modulation bandwidth the interplay of the dominant mode and one side mode has to be enforced. Under these conditions, the modulation bandwidth can be enhanced to more than 70 GHz.endistributed bragg reflector lasersoptical modulationsemiconductor lasersdirect modulation bandwidthdbr laserdetuned bragg reflectordistributed bragg reflector laserdynamical modeltraveling wave equationlongitudinal eigenmodesemiconductor laser diode70 GHz621journal article
