Fundamentals of Photonics

A complete, thoroughly updated, full-color third edition

Fundamentals of Photonics, Third Edition is a self-contained and up-to-date introductory-level textbook that thoroughly surveys this rapidly expanding area of engineering and applied physics. Featuring a blend of theory and applications, coverage includes detailed accounts of the primary theories of light, including ray optics, wave optics, electromagnetic optics, and photon optics, as well as the interaction of light and matter. Presented at increasing levels of complexity, preliminary sections build toward more advanced topics, such as Fourier optics and holography, photonic-crystal optics, guided-wave and fiber optics, LEDs and lasers, acousto-optic and electro-optic devices, nonlinear optical devices, ultrafast optics, optical interconnects and switches, and optical fiber communications. The third edition features an entirely new chapter on the optics of metals and plasmonic devices. Each chapter contains highlighted equations, exercises, problems, summaries, and selected reading lists. Examples of real systems are included to emphasize the concepts governing applications of current interest. Each of the twenty-four chapters of the second edition has been thoroughly updated.

This book introduces classical modal optics and discrete quantum systems using a common mathematical approach based on linear vector spaces. It explores the three key elements of photonic quantum information: the optical bimode, the qubit, and the photon. Both the bimode and qubit are represented as vectors in a two-dimensional linear vector space, but the qubit distinguishes itself through unique properties linked to quantum measurement. While optical bimodes can be mutually coupled, qubits can be entangled, enabling revolutionary quantum information technologies.

A single photon occupying a bimode encodes a qubit, facilitating cryptographic protocols for secure communication. When occupying two bimodes, a photon encodes two qubits, enabling local gates. A photon distributed across spatial modes encodes an image. Entangled photon pairs form two qubits, enabling quantum-state teleportation and quantum networks. Additionally, two photons with spatiotemporal modal entanglement form a biphoton, useful for quantum sensing and imaging with sensitivity surpassing classical limits.

With numerous illustrations, examples, and exercises, the book is ideal for classroom teaching or self-study at the upper-level undergraduate or beginning graduate level. It also serves as an accessible introduction for readers interested in the foundational principles driving the second quantum revolution and its diverse applications in communication, computing, and metrology.
