Title: Modeling of high-speed DFB lasers considering the spatial holeburning effect using three rate equations
Abstract: A new approximated method of analyzing the effect of spatial holeburning on dynamic response of distributed feedback (DFB) lasers is proposed. This method consists of a mode-stability analysis based on the coupled-wave theory and a dynamic analysis utilizing only three spatially independent rate equations. The rate equations can be solved using the calculated result of the stability analysis. The stability analysis predicts that the break of stable single-longitudinal mode (SLM) operation will occur before the modal threshold gain reaches the value for the next mode. Based on this method, calculated results of de characteristics, large-signal responses, and AM responses, including harmonic distortion, are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
