Topological Photonics: Fundamentals and Applications provides an introduction to key principles and advances in our understanding of topology and the design of new photonic materials systems and their applications. Sections cover the necessary fundamental concepts to understand the field, starting from background discoveries in condensed matter physics and delving into describing the underlying concepts and the experimental progress in 1D, 2D, 3D topological photonics systems as well as in synthetic dimensions and non-Hermitian platforms. Other sections highlight the most promising applications of topological photonics, including current progress and the most important challenges.This book is suitable for those working in academia and R&D in the subject areas of materials science and engineering—particularly researchers and practitioners working in the research fields of topological materials, optics, and photonics. - Introduces the fundamental principles of topological photonics and their application in the design of photonic systems - Reviews the models, experimental progress, and challenges and limitations of emerging topological photonic systems - Discusses the future prospects and challenges of applications of topological photonics in lasers, quantum technologies, sensors, and integrated optics
