Abstract
We demonstrate that two chaotic systems, each made by two coupled semi conductor lasers, can be synchronized using direct-optical feedback. T he robustness of the proposed synchronization scheme against mismatch of source parameters and difference in starting conditions is tested b y numerical simulations. Applications to secure data transmission are proposed, namely chaotic masking and chaotic shift keying (CSK).
