Abstract
Electro-optic nonlinear delay dynamics are one of the main alternative approach to external cavity semiconductor lasers, in the context of experimental optical chaos communications setups [1]. In the frame of a recently accomplished European project (PICASSO, FP6-IST-2006-34551), we have demonstrated state of the art performances with a novel electro-optic approach involving the generation of chaotic optical phase broadband carrier from delayed nonlinear non-local feedback oscillator, capable of high quality distant chaos synchronization over a bandwidth exceeding 15 GHz [2]. Our latest investigations were concerned by the demonstration of unprecedented 10Gb/s field experiment of optical chaos communication [3], by the investigation of the critical dispersion issues in broadband electro-optic optical chaos [4], and by the implementation of flexible and reliable physical key-components based security, as well as by the study of the enhanced robustness versus time delay identification for the non-local phase chaos dynamics driven by a pseudo random bit sequence.
