摘要

A numerical model for steady state analysis and analytical expressions for the AM and FM modulation responses of DFB lasers are presented. The small signal modulation responses of 3 phase shift (PS) DFB is investigated. A new method(Vector-Newton method) to obtain multiple-longitudinal-mode of DFB lasers is developed. It is demonstrated that this method is suitable for obtaining multiple-solution of high nonlinear equations. Longitudinal photon density distribution and multiple-longitudinal-mode of 3PS-DFB and simple-DFB lasers are analyzed. The results show that modulation response characteristics of 3PS-DFB laser is as good as that of DFB, and PS can weaken the longitudinal spatial hole-burning(LHSB) effect and is in favor of single longitudinal model operating of lasers.
