Describing a range of photonic principles and techniques, this book gives insight into the underlying physical processes. It presents a detailed treatment of lasers, waveguides, modulators, detectors, non-linear optics and optical signal processing. It also includes sections on photonic crystal fibres, and distributed optical-fibre sensing.

Building on the bestselling "Essentials of Optoelectronics," this edition bears a new title to reflect the dramatic changes in the field. Starting from the principles of photonics and leading to applications, this edition emphasizes guided-wave optics and the devices that depend on it.
