Abstract
We present a refined model for multi-section lasers, introducing an additional equation for material polarization in the well known travelling wave model. We investigate the polarization-induced changes in the spectral properties of the optical waveguide. Finally, we show the relevance of this model for a more realistic simulation of complicated dynamical behaviour of multi-section Distributed Feedback (DFB)-Lasers, such as fast self-pulsations, multi-stability, and hysteresis effects due to mode competition.
