Abstract :
Synchronization quality and message extraction using chaotic laser diode as transmitter-receiver pairs has been experimentally studied. The experimental results demonstrate that the conditions for maximum signal to noise ratio (SNR) of the extracted message are not identical to those for achieving maximum chaos synchronization quality. It is also shown that synchronization quality and message extraction not only depend on having well-matched lasers as transmitter and receiver, but also depend on the roles of the laser diodes.
