Abstract :
The authors demonstrate the optical generation of self-pulsations in complex-coupled DFB laser diodes by selectively positioning the facet with respect to the internal grating. The self-pulsations are accompanied by a strong intensity noise enhancement which partly originates from mode competition. Applying a simple model they determine the imaginary part of the complex coupling coefficient from the self-pulsation frequency
