The book combines recent results on the modelling of nanostructured devices, e.g. Quantum Dot Lasers, Quantum Cascade Lasers and Vertical Cavity Surface Emitting Laser, with mathematical details and an analytic understanding of the underlying nonlinear phenomena. Furthermore possible applications of lasers in cryptography and chaos control will be discussed. This interdisciplinary approach makes it a unique and powerful source of knowledge for anyone intending to contribute to this field of research.

By combining both experimental and theoretical results, the distinguished authors consider solitary lasers with nano-structured material, as well as integrated devices with complex feedback sections. In so doing, they address such topics as the bifurcation theory of systems with time delay, analysis of chaotic dynamics, and the modeling of quantum transport. Another topic is chaos-based cryptography as an example of the technical application of highly nonlinear laser systems.
