Mutual synchronization of two coupled self-oscillators based on GaAs/AlGaAs superlattices

Chaos synchronization in networks of semiconductor superlattices

“…The phenomenon of ZLS between two or more chaotic semiconductor lasers attracted theoretical [32] and experimental [30,31] interest because of promising applications to public-channel cryptography without relying on the number theory, as in other existing methods [22,23]. An attempt in this direction was recently done on synchronization of self-sustained oscillations in two weakly coupled SSLs [33]. The realization of the synchronization of chaotic SSLs is at the center of our work.…”
