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.

Download or read book Slow and Fast Light Using Quantum dot and Quantum well Semiconductor Optical Amplifiers written by Piotr Konrad Kondratko and published by ProQuest. This book was released on 2007 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controlling the group velocity of light has great potential applications in future optical communication, photonic computing, and microwave signal processing. These applications have recently triggered immense experimental and theoretical interest in the research community. Numerous studies report large optical delays while sacrificing many important aspects of engineering feasibility: bandwidth, device compactness, room temperature operation, ease of integration, and minimized signal insertion loss. Slow and fast light in the quantum-dot and quantum-well semiconductor optical amplifiers (SOAs) address many of these characteristics. First, this dissertation presents variable slow light in quantum-dot SOAs using population oscillation in an absorptive medium. Bandwidth tuning of slow light is observed with forward and reverse bias of quantum-dots. Second, the study explores four-wave mixing and population oscillation in a quantum-well gain medium. Control of optical advance and bandwidth is achieved by the medium's electrical bias or the optical pump power. Moreover, the fast light in the cascade of N number of quantum-well SOAs is experimentally and theoretically investigated. The cascaded scheme uses SOA-to-SOA attenuators to achieve active delay-bandwidth control. Finally, a large delay-bandwidth scheme is presented in which slow-to-fast light is observed by means of absorption to gain switching. More than a half cycle of tunable delay at 1 GHz bandwidth is achieved at optical frequencies.

Available in PDF, EPUB and Kindle. Book excerpt: After light became a part of the telecommunication system, the manipulation of light, especially the control of the speed of light, became a focus of research. By using the different approaches of the interaction between light and matter, there have been many successful attempts to slow down the speed of light, even to several meters per second. In the first part of my thesis, I studied pulse propagation in absorptive media (GaAs/AlGaAs multiple quantum well structures-MQWs) to gain insight into the linear interaction between matter and light. Systematic and fundamental measurements of pulse propagation in GaAs/AlGaAs multiple quantum well structures will be presented. These measurements are simulated by treating MQWs as a slab. These measurements and simulations will be compared while using a newly introduced general formalism. In the second part of my thesis, I will present another aspect of manipulating light: all-optical switching. Eric Gansen demonstrated all-optical switching in GaAs/AlGaAs MQWs at cryogenic temperatures. I will demonstrate that the same design of all-optical switch, which is based on polarized virtual carriers, can work without any serious loss of performance at near-room temperatures. Another material used in all-optical switches is Bragg-spaced-quantum-well structures (BSQWs) which are grown by molecular beam epitaxy. The growth of BSQW is challenging because of the associated unusually long growth times. In the last part of this dissertation, I will discuss the challenges involved in MBE growth of 210 period long GaAs/InGaAs BSQWs. By presenting basic characterization measurements of the successful and unsuccessful attempts of BSQW growths, I will demonstrate the challenges of BSQW growth and how they can be addressed.

Download or read book Ultrabroad Bandwidth Slow Light in Semiconductor Nanostructures written by and published by . This book was released on 2008 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slow and fast light enables key functionality in various RF applications and all-optical networks. Semiconductor based schemes offer electrical control of velocity at very high bandwidths in an extremely compact device. Further they operate at room temperature and can be easily integrated into various optical systems. Ultra-fast non-linear processes in semiconductor optical amplifiers (SOAs) have been used to achieve tunable advance and delay at THz bandwidth. For a 700 fs pulse, we show electrically and optically controllable advance of 1.9 ps corresponding to an advance-bandwidth product (ABP) of 2.5. Further, by leveraging self-phase modulation in these devices we extend the performance to an ABP of 3.7. We develop comprehensive theory using density matrix approach to explain the experimental results. Our results show that an ultra-short pulse propagating through the SOA experiences non-linear index change due to spectral-hole burning and wave mixing between different spectral components. We derive analytical expressions for nonlinear index induced by these ultra-fast processes and numerically solve the propagation of an ultra-short pulse through the SOA. Our theoretical predictions agree very well with our experimental results. Finally, we show fast light for two ultra-short pulses separated by 7.2ps which demonstrates the feasibility of this scheme at high bit-rates.

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.
