This book highlights many fundamental aspects of optical fiber transmission engineering while also focusing on current state of the art applications and working examples of digital coherent optical communications. Major engineering themes are reviewed and analyzed in this book, including spectral and time-domain characteristics of multi-level pseudo-random PAM signals, optical QAM and SSB complex modulations and impulse response engineering of linear amplifiers used in next-generation Gbaud transmission systems. This book is balanced between theoretical and numerical simulation approaches, showing numerous working examples developed in Matlab. Presents an in-depth analysis of pseudo-random multi-level signals and high-order complex modulations to support coherent terabit transmission systems; Provides a unified approach to challenging engineering issues encountered in the design of Giga-baud coherent optical transmission systems using high-order complex modulation formats; Reviews engineering themes and provides in-depth analysis, modeling and quantitative examples and solutions of state of the art and future applications.

Theory and Modeling of Cylindrical Nanostructures for High-Resolution Coverage Spectroscopy presents a new method for the evaluation of the coverage distribution of randomly deposited nanoparticles, such as single-walled carbon nanotubes and Ag nanowires over the substrate (oxides, SiO2, Si3N4, glass etc.), through height measurements performed by scanning probe microscopy techniques, like Atomic Force Microscopy (AFM). The deposition of nanoparticles and how they aggregate in multiple layers over the substrate is one of the most important aspects of solution processed materials determining device performances. The coverage spectroscopy method presented in the book is strongly application oriented and has several implementations supporting advanced surface analysis through many scanning probe microscopy techniques. Therefore this book will be of great value to both materials scientists and physicists who conduct research in this area.

This comprehensive, modular treatment of the challenging issues involved in very high-speed optical transmission systems contains all the theory and practical design criteria required to optimise transmission system design. Each chapter covers the theoretical modelling of a given system; chapters are well supported by real-world worked examples and accompanied by MATLAB code and receiver design examples. Critical analysis and comparison of engineering solutions is presented, to make clear the principles underlying system performance optimisation, and a broad range of transmission systems is discussed, including the status and performance demands of the Terabit systems now entering the next generation market. Blending theoretical and practical considerations for high-speed fibre optic systems design, this is an indispensable reference for all forward-looking professionals and researchers in optical communications.
