Available in PDF, EPUB and Kindle. Book excerpt: Four Wave Mixing (FWM) in a semiconductor optical amplifier (SOA) is a third order nonlinear effect, which has various potential applications in high-speed optical communication systems. Continuous-wave (CW) FWM in a 2-section SOA has been experimentally studied. The carrier density modulation and nonlinear gain effects in the semiconductor optical amplifier contribute to the generation of the FWM. A theoretical model of CW FWM and frequency response of FWM using small signal analysis has been developed. Bandwidth of the FWM has been obtained for the first time. Pulsed FWM in the 2-section SOA has also been studied and analyzed. Optical time-division demultiplexing and wavelength conversion using the FWM in the SOA has been demonstrated for optical communication. A tunable Erbium doped fiber laser, which is preferred in the FWM experiments and is potentially an important source for high speed optical communication, has also been investigated. The tunability of the fiber laser is about 40 nm for both CW and mode-locking cases. Actively harmonic mode-locking which happens when the modulation frequency fm = n fc (fc is the fundamental cavity frequency) and rational harmonic mode-locking which happens when fm = (n + 1/p)fc (n, p are both integers) have been studied and analyzed. 22nd order of rational harmonic mode-locking was observed when f m 1 GHz, which is the highest order of rational harmonic mode-locking ever reported. 40 GHz pulse train with pulse width âˆ1⁄47 ps was achieved using rational harmonic mode-locking technique when f m 10 GHz. Stabilization of the mode-locked Er-doped fiber laser with a semiconductor optical amplifier in the cavity has also been studied. The semiconductor optical amplifier contributes in removing the supermode noise and stabilizing the optical pulses.

Available in PDF, EPUB and Kindle. Book excerpt: This invaluable look provides a comprehensive treatment of design and applications of semiconductor optical amplifiers (SOA). SOA is an important component for optical communication systems. It has applications as in-line amplifiers and as functional devices in evolving optical networks. The functional applications of SOAs were first studied in the early 1990''s, since then the diversity and scope of such applications have been steadily growing. This is the second edition of a book on Semiconductor Optical Amplifiers first published in 2006 by the same authors. Several chapters and sections representing new developments in the chapters of the first edition have been added. The new chapters cover quantum dot semiconductor optical amplifiers (QD-SOA), reflective semiconductor optical amplifiers (RSOA) for passive optical network applications, two-photon absorption in amplifiers, and, applications of SOA as broadband sources. They represent advances in research, technology and commercial trends in the area of semiconductor optical amplifiers.Semiconductor Optical Amplifier is self-contained and unified in presentation. It can be used as an advanced text by graduate students and by practicing engineers. It is also suitable for non-experts who wish to have an overview of optical amplifiers. The treatments in the book are detailed enough to capture the interest of the curious reader and complete enough to provide the necessary background to explore the subject further.
Download or read book Advances in Optical Amplifiers written by Paul Urquhart and published by BoD – Books on Demand. This book was released on 2011-02-14 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical amplifiers play a central role in all categories of fibre communications systems and networks. By compensating for the losses exerted by the transmission medium and the components through which the signals pass, they reduce the need for expensive and slow optical-electrical-optical conversion. The photonic gain media, which are normally based on glass- or semiconductor-based waveguides, can amplify many high speed wavelength division multiplexed channels simultaneously. Recent research has also concentrated on wavelength conversion, switching, demultiplexing in the time domain and other enhanced functions. Advances in Optical Amplifiers presents up to date results on amplifier performance, along with explanations of their relevance, from leading researchers in the field. Its chapters cover amplifiers based on rare earth doped fibres and waveguides, stimulated Raman scattering, nonlinear parametric processes and semiconductor media. Wavelength conversion and other enhanced signal processing functions are also considered in depth. This book is targeted at research, development and design engineers from teams in manufacturing industry, academia and telecommunications service operators.

This book was released on 2016-10-21 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines the unique properties of gallium arsenide (GaAs)-based quantum-dot semiconductor optical amplifiers for optical communication networks, introducing readers to their fundamentals, basic parameters and manifold applications. The static and dynamic properties of these amplifiers are discussed extensively in comparison to conventional, non quantum-dot based amplifiers, and their unique advantages are elaborated on, such as the fast carrier dynamics and the decoupling of gain and phase dynamics. In addition to diverse amplification scenarios involving single and multiple high symbol rate amplitude and phase-coded data signals, wide-range wavelength conversion as a key functionality for optical signal processing is investigated and discussed in detail. Furthermore, two novel device concepts are developed and demonstrated that have the potential to significantly simplify network architectures, reducing the investment and maintenance costs as well as the energy consumption of future networks.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive review of the state-of-the art of optical signal processing technologies and devices. It presents breakthrough solutions for enabling a pervasive use of optics in data communication and signal storage applications. It presents presents optical signal processing as solution to overcome the capacity crunch in communication networks. The book content ranges from the development of innovative materials and devices, such as graphene and slow light structures, to the use of nonlinear optics for secure quantum information processing and overcoming the classical Shannon limit on channel capacity and microwave signal processing. Although it holds the promise for a substantial speed improvement, 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 will change in the near future as the tremendous growth of data traffic requires energy efficient and fully transparent all-optical networks. The book is written by leaders in the field.
