Abstract

Optical chaos communications is becoming a hot topic since it is considered as a possible way to improve privacy and security in information transmission. To this end, a message can be encoded within a chaotic carrier generated by an emitter operating in a non-linear regime and decoded by an appropriate receiver. Consequently, the design and implementation of emitters and receivers that operate in a chaotic regime is a very important issue. To this end, two different architectures have been mainly followed: semiconductor lasers subject to all optical feedback and semiconductor lasers subject to electro-optical feedback. In the former, chaos is obtained from the light re-injected into the device that induces the laser to operate in a nonlinear regime. In the latter, the laser acts as a linear device that transforms a chaotic electrical input, generated in a combined electro-optical loop, into chaotic light. Encrypted information within the chaotic carrier can be recovered at a receiver that has to synchronize and match with the emitter. In this talk, both approaches to design the optoelectronic devices will be reviewed.
