Book Quantum Dot Based Semiconductor Optical Amplifiers for O Band Optical Communication

Download or read book Quantum Dot Based Semiconductor Optical Amplifiers for O Band Optical Communication written by Holger Schmeckebier and published by Springer. 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.

Book Advances in Optical Amplifiers

Download or read book Advances in Optical Amplifiers written by Paul Urquhart and published by IntechOpen. This book was released on 2011-02-14 with total page 454 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.

Book Four Wave Mixing in a Highly Nonlinear Media

Download or read book Four Wave Mixing in a Highly Nonlinear Media written by Noor Azura Awang and published by LAP Lambert Academic Publishing. This book was released on 2014-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a comprehensive study of the four wave mixing (FWM) effect in the highly nonlinear fibre (HNLF) and semiconductor optical amplifier (SOA); and their applications. The nonlinearity parameters such as zero-dispersion wavelength (ZDW), chromatic dispersion (CD) and nonlinear coefficient of HNLF has successfully investigated by using several FWM techniques. Results from all techniques have been achieved approximately similar to the manufacturer specification. This technique is then employed for the measurement of the FWM power and FWM efficiency in a SOA, in addition to the gain performance, which is measured using conventional methods. Based on these parameters, a good agreement between experiments and numerical has been obtained. This characterization is important for nonlinear application such as wavelength conversion, fibre optic parametric amplifier (FOPA) and multiwavelength fibre laser. Wavelength conversion is a key for wavelength division multiplexed (WDM) networks. Wavelength converter based on HNLF and SOA are promising candidates for implementing wavelength conversion.

Book Linear and Nonlinear Semiconductor Optical Amplifiers for Next Generation Optical Networks

Download or read book Linear and Nonlinear Semiconductor Optical Amplifiers for Next Generation Optical Networks written by René Bonk and published by KIT Scientific Publishing. 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.
