dc.description.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. en_US
dc.description.abstract Această lucrare este dedicată investigării generării impulsurilor de către un laser cu feedback distribuit (DFB) cu un reflector dispersiv pasiv integrat. Această configurație este tratată în cadrul unui model de ecuații simple pentru purtători adimensionali și numărul de fotoni. Cele două funcții descriu influența reflectorului asupra dinamicii laserului. Rezultatele teoretice arată că, în anumite condiții, laserul funcționează în regim excitabil adecvat pentru generarea de impulsuri. Am identificat valorile adecvate ale parametrilor pentru generarea impulsurilor. Aplicăm mici perturbări sistemului pentru a genera impulsuri periodice. În final, este investigată influența acestor parametri asupra formei impulsurilor. en_US
