In this paper, a simple and cost-effective packaging scheme for improving the modulation bandwidth of directly modulated laser is presented and demonstrated. Combined with the equivalent circuit, the effect of disequilibrium on signal injection efficiency is comprehensively and systematically studied. The simulation and measurement results have a good agreement, which show that the high frequency performance of module can be effectively improved with the proposed packaging scheme. Finally, employing the proposed packaging scheme, we achieve the 3-dB bandwidth of up to 32 GHz regarding the directly modulated semiconductor laser module with the butterfly package.
