Book Description
Optical communication systems carry the bulk of all data traffic worldwide. This book introduces multi-Terabit/s transmission systems and three key technologies for next generation networks. A software-defined multi-format transmitter, an optical comb source and an optical processing scheme for the fast Fourier transform for Tbit/s signals. Three world records demonstrate the potential: The first single laser 10 Tbit/s and 26 Tbit/s OFDM and the first 32.5 Tbit/s Nyquist WDM experiments.

Book Description
We study the potential of the silicon-organic hybrid (SOH) platform for integrated optics. The unique properties of selected organic materials are added to silicon devices made with CMOS-based processes. We investigate the feasibility of this approach by making prototypes of key components in form of photonic integrated circuits: SOH lasers and SOH modulators are designed, fabricated, post-processed, and characterized. Application scenarios are identified.

Book Description
In this book, the first high-speed silicon-organic hybrid (SOH) modulator is demonstrated by exploiting a highly-nonlinear polymer cladding and a silicon waveguide. By using a liquid crystal cladding instead, an ultra-low power phase shifter is obtained. A third type of device is proposed for achieving three-wave mixing on the silicon-organic hybrid (SOH) platform. Finally, new physical constants which describe the optical absorption in charge accumulation/inversion layers in silicon are determined.

Book Description
Self-coherent receivers are promising candidates for reception of 100 Gbit/s data rates in optical networks. Self-coherent receivers consist of multiple optical delay interferometers (DI) with high-speed photodiodes attached to the outputs. By DSP of the photo currents it becomes possible to receive coherently modulated optical signals. Especially promising for 100 Gbit/s networks is the PolMUX DQPSK format, the self-coherent reception of which is described in detail.

Book Description
Optical fiber communication has indeed come a long way from the 1970s. From being a favorite subject of science fiction movies and books, today it is believable reality that finds applications in many spheres. This book explores the dominant role of optical fiber communication in the telecommunication industry, as it caters to the ever-increasing demand for high data rate transmission. It provides an overview of the history and origin of optic fiber communication and discusses the manufacturing techniques, characteristics and current applications of optic fibers. It also describes the types of fiber links in use today, the elements of optic fiber communication and the design considerations. It finally presents a brief outlook of the proposed new technologies to overcome the limitations of current optical fibers and enhance their data carrying capacity to meet the emerging demands worldwide. The book is targeted at students (as an introductory course material) and those who are not familiar with the subject and are eager to know more.

Book Description
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.
