摘要：

A computer model is proposed to analyze the characteristics of distributed feedback lasers. The model is based on time-dependent coupled wave equations, with spontaneous emission taken into account. In order to avoid uncertain phase factors in spontaneous emission, we present a new method to convert field equations to power equations in a matrix format before computation. The steady-state LI curve and transient response to the pulse excitation are calculated in the lambda/4 phase-shifted distributed feedback (DFB) lasers. The longitudinal variations of the carrier and photon densities as well as of the refractive index are considered in the model.
