Large-signal dynamic model for gain-coupled DFB lasers based on the transmission-line laser model

摘要

New scattering matrices are developed for the transmission-line laser model (TLLM) to enable the dynamics of gain-coupled DFB lasers to be studied. The resulting model is able to simulate large-signal transient responses and spectral characteristics of gain-coupled DFB semiconductor lasers, and gives threshold gains in excellent agreement with analytical formulations.
