Mid-infrared Quantum Cascade Lasers for Chaos Secure Communications

This private transmission is made possible by the chaos synchronization of two twin QCLs. Chaos in QCLs can be generated under optical injection or external optical feedback. Depending on the parameters of the optical feedback, QCLs can exhibit several non-linear phenomena in addition to chaos. Similarities exist between QCLs and laser diodes when the chaotic dropouts are synchronized with an external modulation, and this effect is known as the entrainment phenomenon. With a cross-polarization reinjection technique, QCLs can generate all-optical square-waves. Eventually, it is possible to trigger optical extreme events in QCLs with tilted optical feedback. All these experimental results allow a better understanding of the non-linear dynamics of QCLs and will extend the potential applications of this kind of semiconductor lasers.
Olivier Spitz received his Ph.D. in electrical engineering from Télécom Paris, France, in 2019 and is now a postdoctoral researcher with Institut Polytechnique de Paris, France, working on applications of mid-infrared quantum cascade lasers. He has been a visiting scholar in the Electrical and Computer Engineering Department of the University of California Los Angeles, USA, and in the Institut für Angewandte Physik of the Technische Universität Darmstadt, Germany. Dr. Olivier Spitz also works in collaboration with the Laboratoire de Physique of École Normale Supérieure Paris, France. His research interests include nonlinear dynamics, free-space communications, and neuromorphic photonics.
