A novel dynamic transmission-line-laser-modeling-based model of the multiple phase shift distributed feedback (DFB) lasers has been proposed in this paper. The dynamic and static characteristics of three phase shift (3PS) DFB structures are analyzed based on this model. The longitudinal carrier density distribution of quarterly wavelength shifted (QWS) DFB LDs and 3PS DFB LDs are compared. Our results show that 3PS DFB structure has a more uniform longitudinal carrier density distribution; hence such a structure reduces the spatial hole burning effect and strengthens the stability of single longitudinal mode.
