Synchronization of chaos in microchip lasers and its communication applications

Abstract

We overview some experimental and numerical demonstrations on the synchronization of chaos and its communication applications using Nd:YVO 4 microchip solid-state lasers. Synchronization of chaos is achieved with several coupling configurations. Several encoding and decoding schemes for communication applications are also demonstrated by using the synchronization of chaos in microchip lasers. A new approach to secure communications using chaos based on information theoretic security is introduced. To cite this article: A. Uchida, S. Yoshimori, C. R. Physique 5 (2004).
