A theoretical model of a self-pulsating three section DFB-laser with an integrated phase tuning section is established. It is based on traveling wave equations and the standard carrier rate equations. As the key conditions for obtaining self-pulsations the spectral correlation of the different device sections are considered. The specific roles of each section are discussed and the theoretical results are compared to experimental measurements on these devices.
