Book Description
This book describes the fascinating recent advances made concerning the chaos, stability and instability of semiconductor lasers, and discusses their applications and future prospects in detail. It emphasizes the dynamics in semiconductor lasers by optical and electronic feedback, optical injection, and injection current modulation. Applications of semiconductor laser chaos, control and noise, and semiconductor lasers are also demonstrated. Semiconductor lasers with new structures, such as vertical-cavity surface-emitting lasers and broad-area semiconductor lasers, are intriguing and promising devices. Current topics include fast physical number generation using chaotic semiconductor lasers for secure communication, development of chaos, quantum-dot semiconductor lasers and quantum-cascade semiconductor lasers, and vertical-cavity surface-emitting lasers. This fourth edition has been significantly expanded to reflect the latest developments. The fundamental theory of laser chaos and the chaotic dynamics in semiconductor lasers are discussed, but also for example the method of self-mixing interferometry in quantum-cascade lasers, which is indispensable in practical applications. Further, this edition covers chaos synchronization between two lasers and the application to secure optical communications. Another new topic is the consistency and synchronization property of many coupled semiconductor lasers in connection with the analogy of the dynamics between synaptic neurons and chaotic semiconductor lasers, which are compatible nonlinear dynamic elements. In particular, zero-lag synchronization between distant neurons plays a crucial role for information processing in the brain. Lastly, the book presents an application of the consistency and synchronization property in chaotic semiconductor lasers, namely a type of neuro-inspired information processing referred to as reservoir computing.

Book Description
Lasers generally emit radiation, which is either simply linearly polarized or unpolarized and stochastically polarized. Contrary to these common lasers, all orthogonally polarized lasers simultaneously emit radiation in two linear polarization states, both exactly orthogonally oriented to each other. Due to this orthogonality, both polarized components in the beam are independent of each other to a high degree and the studies presented in this book make clear that this feature can give a strong advantage in certain laser applications, for instance in high-precision measurements. Orthogonal Polarization in Lasers: Physical Phenomena and Engineering Applications summarizes the basics and advanced research results of orthogonally polarized lasers, birefringence laser cavities, and their applications. The authors include a number of figures, experimental designs, and measurement curves to enable the reader to not only learn the basic principles and technologies but also to understand many applications in modern engineering and to start their own R&D projects. The book covers polarization effects, which are of fundamental importance across various disciplines of science and technology. Includes a number of figures, experimental designs, and measurement curves to help readers learn the basic principles and start their own R&D projects. Discusses many types of relevant lasers (helium/neon lasers, ND:YAG lasers, semiconductor lasers, laser diodes). Written by multiply-published authors in the subject area. Contains material useful for metrology applications. This book is intended for use by researchers, postgraduates, and engineers working in laser science, optics, and measurement and testing, while senior undergraduate students working in optical and laser science can use the book for advanced understanding in their field.

Book Description
Chaotic Signals in Digital Communications combines fundamental background knowledge with state-of-the-art methods for using chaotic signals and systems in digital communications. The book builds a bridge between theoretical works and practical implementation to help researchers attain consistent performance in realistic environments. It shows the possible shortcomings of the chaos-based communication systems proposed in the literature, particularly when they are subjected to non-ideal conditions. It also presents a toolbox of techniques for researchers working to actually implement such systems. A Combination of Tutorials and In-Depth, Cutting-Edge Research Featuring contributions by active leading researchers, the book begins with an introduction to communication theory, dynamical systems, and chaotic communications suitable for those new to the field. This lays a solid foundation for the more applied chapters that follow. A Toolbox of Techniques—Including New Ways to Tackle Channel Imperfections The book covers typical chaos communication methods, namely chaotic masking, chaotic modulation, chaotic shift key, and symbolic message bearing, as well as bidirectional communication and secure communication. It also presents novel methodologies to deal with communication channel imperfections. These tackle band-limited channel chaos communication, radio channels with fading, and the resistance of a special chaotic signal to multipath propagations. In addition, the book addresses topics related to engineering applications, such as optical communications, chaotic matched filters and circuit implementations, and microwave frequency-modulated differential chaos shift keying (FM-DCSK) systems. Insights for Both Theoretical and Experimental Researchers Combining theory and practice, this book offers a unique perspective on chaotic communication in the context of non-ideal conditions. Written for theoretical and experimental researchers, it tackles the practical issues faced in implementing chaos-based signals and systems in digital communications applications.
