Abstract :
A report is presented on the first synchronisation results with two optoelectronic nonlinear delayed feedback subsystems generating sequences of regularly clocked picosecond light pulses with chaotically distributed amplitude. chaos encoding and decoding of pseudorandom binary information is also demonstrated. the proposed principle is a promising way for securing high-rate communications with chaos at the physical level.
