Optical Waveguide Theory

This text aims to provide a comprehensive, standalone treatment of the theory of optical waveguides. We have attempted to emphasize the underlying physical processes and highlight conceptual aspects, while developing the mathematical analysis to align with physical intuition. Additionally, we offer extensive supplementary sections to compensate for any deficiencies in the mathematical background and ensure a self-consistent and rigorous mathematical approach. To facilitate understanding, each chapter primarily focuses on a single idea and is therefore relatively short. Furthermore, over 150 problems with complete solutions are provided to demonstrate the applications of the theory. Due to the simplicity of the approach and numerous examples, this book is accessible to students. Many fundamental topics are presented here for the first time, but even more importantly, the material is significant.
