Paper Abstract

Chaos-based secure communication is intended to operate as an additional encryption mean at the physical layer, with the unique capability for operating at several 10s of Gb/s. Different chaos generators have been recently explored for optical telecommunications, among which three setups were particularly interesting in terms of encryption speed capability: the all-optical external cavity semiconductor laser, the direct optoelectronic feedback semiconductor laser, and the nonlinear electrooptic feedback. The latter solution was mainly investigated by our group during the last 5 years. We report its numerous advantages in terms of chaos complexity (attractor dimension as high as several hundreds have been obtained), architecture reliability (different chaos generator have been performed experimentally), encryption bandwidth capability (more than 30GHz chaotic spectrum has been observed), stability, and decoding quality. The potential for high speed operation was recently demonstrated with an electrooptic chaos generator at 3Gb/s, with BER as low as 10-9}.
