Ap. Napartovich et Ag. Sukharev, DECODING OF INFORMATION IN A SYSTEM WITH A CHAOTIC LASER CONTROLLED BY A CHAOTIC SIGNAL, Quantum electronics, 28(1), 1998, pp. 81-84
An optical information channel, based on two synchronised chaotically
operating lasers with periodic pumping of the active medium, is consid
ered. A study is reported of the dynamics of this laser system when ch
aotic radiation modulated by an external signal is injected. It is sho
wn that information carried by a chaotic signal transmitted by such a
channel can be retrieved and an estimate of the permissible width of t
he spectrum of the information signal is estimated.
