This book was released on 2007 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation mainly focuses on two closely-related research topics about Vertical Cavity Semiconductor Optical Amplifiers (VCSOAs). One is theoretical study, modeling, and characterization of the nonlinear gain characteristics of VCSOAs due to the dependence of nonlinear refractive index on carrier concentration in its Fabry-Perot (FP) cavity; the other is the experimental investigation of the feasibility of all-optical logic operations. First, the theoretical study and demonstration of Wavelength Bistability (WB) and Multiple Bistability (MB) in a VCSOA are presented. It is proved both experimentally and theoretically that WB and Power Bistability (PB) are inter-related through the same bistable switching points. MB is observed by sweeping the optical input power, with input wavelength fixed at the longer-wavelength side of two Polarization-Dependent Gain (PDG) windows of a VCSOA while the input polarization direction is set to a specific angle with respect to two intrinsic principal axes of material birefringence in the VCSOA. Secondly, a cascadable All-Optical Inverter (AOI), All-Optical Flip-Flop (AOFF) and All-Optical Pass Transistor (AOPT) are proposed and demonstrated experimentally based on VCSOAs. The operation of cascadable AOI is based on three types of nonlinearities in a VCSOA: Cross-Gain Modulation (XGM), nonlinear gain characteristics (including optical bistability), and polarization gain anisotropy. The demonstrated AOI shows fast switching time

This book was released on 2014-05-12 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, semiconductor optical amplifiers (SOAs) are studied with a view to linear and nonlinear applications in next-generation optical networks. Quantum-dot SOAs can be optimized for linear amplification of signals with different modulation formats and multiplexing techniques. Conversely, bulk SOAs can be easily optimized for operation in the nonlinear regime. However, due to the fast carrier recovery times in QD SOAs we also look into nonlinear applications with these devices.

Available in PDF, EPUB and Kindle. Book excerpt: A traveling-wave semi-conductor laser amplifier (TWA) 1-4 can greatly simplify optical repeaters used in wavelength-division-multiplexed (WDM) systems, since its wide gain bandwidth width allows a single TWA to simultaneously amplify signals of different wavelengths. Even though such system performance in the linear gain regime is determined only by amplifier noise properties 5,6, the onset of nonlinear effects in optical amplifiers result in crosstalk 7. Nonlinear effects in optical amplifiers have opposite aspects; (1) unfavorable for linear amplifications where any nonlinearity impairs the performance and should be avoided, but (2) favorable for highly efficient nonlinear operation 8,9 due to a large optical gain compared with passive/absorptive nonlinear materials. Two significant nonlinear effects are signal gain saturation 10 occurring for a large input signal and nearly degenerate four-wave mixing (NDFWM) 11,12 occurring for multifrequency input signals, as summarized in Fig. 1 (13). The dominant nonlinearity in the semiconductor laser amplifiers (SLAs) restilts from changes in the injected-carrier density as a result of signal amplification. Signal gain saturation arises from the reduction in DC carrier component ndc, while the NDFWM is attributed to the generation of a carrier beat, component n omega at beat frequency omega.

Available in PDF, EPUB and Kindle. Book excerpt: This invaluable book 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.

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.
