Suitable as both a textbook and as a reference source, Lightwave Engineering is divided into two parts: the first section presents a comprehensive introduction to lightwave engineering using plane wave, while the second section provides an in-depth analysis of lightwave propagation in terms of electromagnetic theory. This book features useful appendices that offer formulas for Fourier transform, derivation of Green's theorem, vector algebra, Gaussian function, cylindrical function, and more. Additional topics covered include fundamentals of interferometers and resonators, guided wave, optical fibers, and lightwave devices and circuits.
