A Field Theory Approach to Photonics

A Field Theory Approach to Photonics Synopsis

This book focuses on providing an easy and beginner's friendly introduction to the theoretical framework of classical and quantum field theory, one of the most powerful tools available to theoretical physicists nowadays. In particular, it aims at carefully explaining, with worked-out examples, how this framework can be applied to different situations in Photonics, both at the classical and quantum level, to gain insight on both the propagation and the interaction of the electromagnetic field with complex photonic nanostructures, such as multimode optical fibres, 2D materials and metasurfaces.

Key Features:

Comprehensive reference for field theoretical methods in Photonics Easily accessible introduction to theoretical physics models in Photonics Unifying view of classical and quantum properties of light-matter interaction A versatile platform to approach complex problems in Photonics Contains several worked examples of the primary calculations, both in the classical and quantum case, to help the reader getting familiar with the formalism, thus granting them access to the subject in an easy, beginner's friendly manner
