Abstract :
The synchronization process of DFB lasers has been described taking into account the coupled-wave equations and the spatial hole burning effect that results. The locking bandwidth was deduced in function of the grating parameters so as to highlight its importance in relevant applications. The method advantage is not only limited to the detailed description of injection locking in simple DFB lasers but relies on the possibility of studying different laser structures like those having complex coupling factors or those having different sections. Much of the research motivation is founded on the need to provide reliable and tunable microwave photonic sources that will allow high frequency feeding of antenna arrays
