Downloading the PDF version of "Optical Communication Systems" by John Gowar can be beneficial for several reasons: co-authoring another highly-regarded book
John Gowar is a recognized electrical engineer with a keen focus on the intersection of device physics and system design. He has made significant contributions to the field of power electronics, co-authoring another highly-regarded book, Power MOSFETs: Theory and Applications . This background likely influenced his systematic and practical approach in Optical Communication Systems , enabling him to explain not just how components work, but how they perform in real-world constraints.
"Optical Communication Systems" by John Gowar is a comprehensive textbook that covers the fundamental principles and applications of optical communication systems. The book was first published in 1986 and has since become a classic reference in the field. It provides a detailed treatment of the subject, covering topics from the basics of optical communications to advanced topics such as coherent optical communication systems and optical soliton communication systems.
