Abstract

The combined laser model based on transmission line laser mode (TLLM) is extended to investigate intensity modulation (IM) response and frequency modulation (FM) response of SGDBR lasers in this paper. While carrier-depended refraction index, spontaneous emission noise and their coupling are included in the consequent dynamic frequency shift and intensity fluctuation can reflect dynamics of SGDBR lasers in more real circumstances. Simulation results indicate that direct modulation bandwidth increases as bias current increases in IM. Frequency chirp in small signal IM and the fluctuation of output optical power in FM are also discussed.
