Opto-electronic systems subject to delayed feedback can generate very rich dynamics which are desired for many applications. These systems offer reliability, high bandwidths, high power efficiency and integration facility on networks or optics. Typically, they consist of semiconductor lasers subject to optical delayed feedback or electro-optical delayed feedback. In this seminar, I will discuss the versatile use of opto-electronic systems for some real-world applications : On one hand, I will discuss the security issues in chaos cryptosystems based on opto-electronic delay systems. Then, I will deepen these discussions on the generation of high-quality non-deterministic random bits using broadband chaotic signals. On the other hand, I will show that stable periodic regimes generated in these systems are useful for generating ultra-pure microwaves with very low phase noise while the stable steady state regime can be suited for the newly introduced brain-inspired computational paradigm, namely reservoir computing.
