In this paper, a longitudinal transmission-line model for two section distributed feedback (DFB) lasers is developed. The characteristic impedances of active periodic structures are derived. A two section DFB laser is described as a transmission-line network, with each section represented by a transmission-line segment with a corresponding characteristic impedance. Static and dynamic analysis of two section DFB lasers is demonstrated. The reflections at the junctions between sections are evaluated more accurately. The resonant condition of the equivalent transmission-line network is used to reformulate the rate equations.
