This paper presents a new model for the numerical analysis of distributed feedback (DB) semiconductor lasers, and analyzes the stability of DFB lasers above their Q values. The model considers the hole burning effect and the nonlinear gain effect, and proposes a numerical method to solve the DFB laser matrix model by using the vector method. Compared with the Newton-Raphson (NR) method, the vector method avoids complicated autonomous operations and saves Computing time The article also analyzes the single-mode stability problem of DFB in the presence of non-laser shooting model. The numerical model proposed in this paper is suitable for the characterization of DFB lasers with various structures.
