'Professor Brian Culshaw has written a non-mathematical textbook that introduces the fundamentals of how light interacts with matter and reviews many of the diverse applications of optical systems in everyday life. This book is thus written at a level appropriate for undergraduate science or engineering students. Although advanced mathematical concepts are invoked … mathematical derivations are avoided and simple explanations are used throughout the book. The author reviews the interactions between light and matter … and then considers how the length scale of structures or features in matter can influence this interaction … a review of the many applications of photonics, ranging from lighting, digital communication, to even metal welding and cutting … Hence Introducing Photonics manages to successfully convey the diversity, excitement, and impact of photonic applications in modern society, without the mathematical details.'
