The paper extend a integrated TLLM model to investigate the characteristics of directly modulated semiconductor lasers (DMLs). The model combines an equivalent circuit laser model and a transmission-line laser model (TLLM) for both electrical and optical issues. Microwave aspects such as high-frequency parasitic effects and impedance matching networks of laser diodes can be included in equivalent...

The authors demonstrate a compensation scheme to reduce the frequency chirp associated with directly modulated sampled grating distributed Bragg reflector tunable lasers. Experimental results obtained show that the direct modulation of the laser's gain section results in a large frequency chirp of 25 GHz. However, by simultaneous modulation of the laser's phase section this large frequency chirp can...
