Abstract
This paper is devoted to investigation of pulse generation by a distributed feedback (DFB) laser with an integrated passive dispersive reflector. This configuration is treated in the framework of the simple rate equation model for dimensionless carrier and photon numbers. The two functions describe the influence of reflector on the laser dynamics. The theoretical results show that under certain condition the laser is operating in excitable regime suitable for pulse generation. We have identified the appropriate values of parameters for pulse generation. We apply small perturbation to the system in order to generate periodic pulses. Finally, the influence of these parameters on shape of pulses is investigated.
