“…The switching power of a fiber-based NLDC operating in the multi-beatlength regime may be further reduced by injecting an input elliptically (as opposed to circularly) polarized beam [21,22]. Let us set s 1 ðf ¼ 0Þ ¼ e cosð2/Þ, s 1 ðf ¼ 0Þ ¼ e sinð2/Þ, and…”

PrefaceAlthough it holds the promise for substantial processing speed improvements, in today's communication infrastructure optics remains largely confined to the signal transport layer, as it lags behind electronics as far as signal processing is concerned. This situation is bound to change in the near future as the tremendous growth of data traffic requires the development of new, energy efficient, and fully transparent all-optical networks for telecom and datacom applications. This book provides a comprehensive review of the state of the art of all-optical devices based on nonlinear optical materials for applications to optical signal processing. Contributors to this book present breakthrough solutions for enabling a pervasive use of optics in data communication and signal storage applications. The book content ranges from the development of innovative materials and devices, such as graphene and photonic crystal structures, to the use of nonlinear optical signal processing for secure quantum information processing, for increasing the transmission channel capacity, and for enhancing the performance of broadband radio frequency signal processing. The book is expected to benefit all researchers in the fields of optical communications, photonic devices for optical signal processing, nonlinear guided wave optics, quantum information processing, and microwave photonics, including senior undergraduate and postgraduate students and industry researchers.Chapter 1 summarizes the recent progress in materials and structures for alloptical signal processing that employ either second-or third-order optical nonlinearities. The dominant choice for quadratic materials is provided by periodically poled lithium niobate waveguides. For cubic nonlinearities, the range of materials ranges from glasses to both active and passive semiconductor devices: a brief summary of the advantages and disadvantages of each class of materials and device structure is provided. In Chap. 2, recent advances in new nonsilicon CMOScompatible platforms for nonlinear integrated optics are revised, focusing on Hydex glass and silicon nitride. The promising new platform of amorphous silicon is also briefly discussed. These material systems have opened up new functionalities such as on-chip optical frequency comb generation, ultrafast optical pulse generation, and measurement. Chapter 3 overviews the principles of optical switching devices, based on either optical or electrical control signals, which permit to avoid the v

“…These fibers are essential for interferometric applications, [1][2][3][4][5] where the polarization state of the light should be maintained and not be affected by external perturbations. To achieve this objective, either the slow or the fast birefringent axis of the fiber should be aligned to the polarization direction of the input beam with a great accuracy ͑better than 0.5 deg since Ref.…”
