From the modulation of light waves to amplification, compensation of loss, and routing of channels, Photonic Signal Processing: Techniques and Applications presents comprehensive coverage of optical communications systems and advanced photonic communications. This book presents an overview of amplified lightwave communications, describing lightwave sources for ultra-high transmission and optical transmitters. It provides an understanding of fundamental and advanced optical fibers, optical receivers, and lumped and distributed optical amplifiers. The book also discusses principles and implementation of advanced photonic communication systems as well as their essential components.
