Mid-infrared Quantum Cascade Lasers for Chaos Secure Communications (eBook)

The mid-infrared domain is a promising optical domain because it holds two transparency atmospheric windows, as well as the fingerprint of many chemical compounds. Quantum cascade lasers (QCLs) are one of the available sources in this domain and have already been proven useful for spectroscopic applications and free-space communications. This thesis demonstrates how to implement a private free-space communication relying on mid-infrared optical chaos and this requires an accurate cartography of non-linear phenomena in quantum cascade 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.
