The Second Edition of this successful textbook provides a clear, well-written introduction to both the fundamental principles of optics and the key aspects of photonics to show how the subject has developed in the last few decades, leading to many modern applications. Optics and Photonics: An Introduction, Second Edition thus provides a complete undergraduate course on optics in a single integrated text, and is an essential resource for all undergraduate physics, science and engineering students taking a variety of optics based courses. Specific changes for this edition include: New material on modern optics and photonics Rearrangement of chapters to give a logical progression, comprising groups of chapters on geometric optics, wave optics and photonics Many more worked examples and problems Substantial revisions to chapters on Holography, Lasers and the Interaction of Light with Matter
