Basic scientific achievements

Conditions for the stable synchronizations between the laser systems with different types were established; this fact is of immense importance for the  laser chaos based communication systems.

There are different types of chaotic synchronization. In an anticipating synchronization the driven system  can be synchronized to the future state of the driver system. This type of synchronization is very important for the information processing, in the noninvasive diagnostics, etc.

Chaos synchronization is also exploited for the construction of dynamical logic gates AND, NAND, OR, XOR by controlling the synchronization error. This result may be used for the purpose of more compact and speedy computational hardware with reconfigurable properties.

By investigating the possibility of both in-phase (complete) and  anti-phase (inverse)  synchronization between the laser systems we  have established that depending on the coupling rates between the systems a transition from the in-phase (complete) synchronization to the anti-phase (inverse) synchronization might occur. The results are important for the disruption of the spread of the certain infectious diseases in human populations. In the power system such transitions could be used for the prevention of the power blackout. Research in the lab has also established that chaos control methods can be used for the species preservation purposes.

The possibility of THz generators based on the synchronized Josephson contacts is established.

Chaos can be harnessed with chaos.
