Utilisation of chaotic laser diodes in optical communication systems was studied. It was shown that synchronization of two chaotic external-cavity semiconductor diode lasers could be done for many hours continuously and quality of synchronization was expressed in terms of slope (m) and its variation. Control of degree of synchronization was done by the coupling coefficient between the master and slave lasers. Experimental verification of a synchronization condition, which related the feedback rate to the master and slave lasers and the coupling coefficient between them was done.
