Nanophotonics is a key branch of nanoscience with a variety of applications in device technology. This book acquaints the reader with photonic crystals and metamaterials. Introduction to Nonlinear Optics of Photonic Crystals and Metamaterials, Second Edition presents concise examples illustrating the basic principles of the field, embedding a discussion of current and future device applications in a theoretical account of the non-linear behaviour of light at nanoscale to produce an informative and authoritative introduction to the subject for students trying to advance rapidly amongst the vanguard of modern applied physics and engineering.

Focusing on the engineered optical systems that have been of recent interest in physics, engineering, and applied mathematics, Professor McGurn describes the fundamentals of a range of important subjects in nanophotonics, including waveguides and their barriers, the negative refraction index, perfect lenses, second harmonic generations, optical circuits, plasmonics, optical computing, and Anderson localization phenomena. Direct and reciprocal lattices, Brillouin zones, Block functions, and the properties of stop and pass bands are introduced, and computer simulation treatments are applied to the problems generated.

This revised second edition features a study of basic optical circuits based in photonic crystal and metamaterial technology, a discussion of disordered systems including Anderson localization and a review of recent device applications.

This book is an excellent access point for the current research literature in nanophotonics. Pitched at an accessible level, this survey of some of the most important fundamentals of the field is ideal for researchers, undergraduate and graduate students, as well as self-taught students looking to expand their current field of interest.
