From the reviews: “This reference discusses the most recent contributions to nonlinear impairment in fiber optics communications. … should be of interest to professionals and graduate students in the fields of optical sciences, physics and applied mathematics. … this book connects the important issue of high demands for a large channel capacity with high spectral efficiency and flexible network design. … this highly recommendable book analyzes all-optical regenerator schemes for phase encoded signals in order to suppress linear and nonlinear phase noise in systems.” (Axel Mainzer Koenig, Optics & Photonics News, October, 2011)
