First published by Prentice Hall, John Gowar’s textbook provides a comprehensive introduction to the design, analysis, and operation of optical fiber communication links. The book is highly regarded for its rigorous mathematical foundations and clear physical explanations. It serves as an excellent resource for advanced undergraduates, postgraduates, and practicing engineers who need a deep understanding of optical waveguides and optoelectronic devices.
