Abstract
A new method of controlling the phase of a propagating wave coupled be tween the laser facets and the internal loss grating in a complex-coup led DFB laser diode is introduced. The overlap between the optical mod e and the lossy region is deduced from the measured threshold current. The method permits a controlled change of the operating conditions an d allows a systematic study of the influence of an absorber on thr las er dynamics.
