摘要
Abstract
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 for the first time.A new method(Vector-Newton method) to obtain multiple-longitudinal-mode of DFB lasers is used.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 mode operating of lasers.关键词
