Abstract:
We report the results of numerical and experimental investigations of the electrooptical behaviour of an external cavity diode laser device composed of a semiconductor laser and a distant Bragg grating, which provides an optical feedback. The travelling wave model was used to simulate and analyse the nonlinear dynamics of the considered laser device. Different modelling approaches for gain and refractive index change functions have been considered. It is shown, that the simulated behaviour of the electro-optical characteristics is in good agreement with experiments.
