The numerical analysis of dynamic properties of the distributed feedback laser (DFB) is presented. The model is based on coupled rate equations, which can describe mutual relations between a photon number, an electron number and an optical phase in the active region of the DFB laser. The presented numerical approach includes intrinsic fluctuations of laser parameters and laser noises caused by these fluctuations to the model using the fourth order Runge-Kutta method. The DFB model can be consequently applied for a purpose of advanced simulations performed in the complete optical transmission model.

.Zaprezentowano analizę numeryczną w łaściwości dynamicznych lasera typu DFB. Model bazuje na sprzężonych równaniach opisującychwzaje,mne relacje miedzy liczbą fotonów, liczbą elektronmów I fazą optyczną cześci aktywnej lasera. W modelowaniiu wykorzystano metodę Runge-Kutta czwartego rzędu. W opracowanym modelu uwzględnmiono możliwość fluktuacji parametrów lasera i wynikające stąd szumy.
