Fiberoptics setup for chaotic cryptographic communications

In this paper we present a fiberoptics setup which can be easily configured for different experiments on chaos generation, chaos synchronization and optical chaotic cryptography using semiconductor lasers. Long and short cavity, open and closed loop configurations are easily implemented with minor changes of the basic setup, allowing for a comparison of their performances using various encoding methods. Different transmission media, possibly including optical amplifiers, can be also tested. To cite this article: V. Annovazzi-Lodi et al., C. R. Physique 5 (2004).
