Book Description
The NATO Advanced Study on Waveguide Optoelectronics was held at the Kelvin Conference Centre in Glasgow, Scotland, between 30 July and 10 August 1990. In aliSO students and 15 lecturers attended the ASI. The successof the meeting was due not only to the high quality of the presentations but also to the enthusiasm ofall the participants and their willingness to take part in the discussion and poster sessions. 1990 was also the year in which Glasgow was the European City of Culture. This resulted in interesting diversions during the middle weekend of the school and also made the meeting probably the first NATO ASI to share accommodation with the Bolshoi Opera and Ballet who gave memorable performances as partof the City's celebrations. This volume is, however, intended to be more than merely a record of presentations at the NATO meeting. The authors have written their material so as to be approachable by a first degree graduate with some background in optoelectronics. The principal materials considered are the III-V semiconductors, lithium niobate and silica. Recent developments towards optoelectronic integration in semiconductors, developments in devices fabricated in doped silica and doped lithium niobate, and developments in all-optical switching networks are highlighted. The role of reduced dimensional structures is examined in some detail.

Book Description
Properties of quantum-well(QW) structures have proved useful in providing enhanced device characteristics and even in generating new device applications. This book presents a theory needed to understand the properties of QW structures, as well as the rules employed in the design of photodetectors based on QWs. A theoretical model is presented evaluating gain from the QW structure based on IV-VI semiconductor materials. The experimental and theoretical results concerning coupled QW structures are discussed. Semimagnetic quantum wells attract great attention due to potential device application in the field of spintronics. A study of three groups of semimagnetic structures is presented. Magnetoexcitons dispersion in coupled quantum wells are discussed using the Bethe-Salpeter formalism. Also presented are: high-resolution electron energy loss spectroscopy measurements on surface plasmon dispersion in systems exhibiting quantum well states; a review of different ways to achieve a spin splitting of two-dimensional electron and hole sub-bands; a review of two approaches to the quantisation of the particle motion in an infinite square; a study of the different disordered electron systems with various disorder strengths; and a study of quantum states of Double Quantum Wells and hydrogen-like molecules. An optical gain using the new material system InGaAsN for the operation of QW based semiconductor lasers is evaluated as well.

Book Description
Optical interconnects have the potential to help create faster, more powerful computers that use far less energy than they currently do. However, to accomplish this goal, key material and device design breakthroughs must first occur. This Ph. D. dissertation focuses on developing the technology for one component of future optical interconnects, the optical modulator. Ge/SiGe quantum wells exhibit the quantum-confined Stark effect, the strongest high-speed electroabsorption modulation mechanism available in a CMOS-compatible material. We begin by examining the ultrafast carrier dynamics of these quantum wells as a way to understand the fundamental limitations to optical modulators which rely on this material. Using a pump-probe experimental setup, we measured the intervalley scattering time of electrons from the direct valley to the indirect L valley in the conduction band of the germanium wells to be ~185 fs. We also measured field screening in these quantum wells and modeled its recovery through diffusive conduction within 120 ps. This improved understanding of Ge/SiGe quantum wells allowed us to design a waveguide-integrated modulator that relies on selective area growth of this material in thick silicon-on-insulator waveguides. Selective area quantum well waveguide modulators offer the potential of high contrast ratios, low operating energies, and low loss. We developed a novel growth substrate fabrication process to enable high quality selective area growth of Ge/SiGe quantum wells with minimal sidewall growth. We then fabricated selective area modulators integrated with SOI waveguides, and present here preliminary results from these devices.

Book Description
A recent major development in high technology, and one which bears considerable industrial potential, is the advent of low-dimensional semiconductor quantum structures. The research and development activity in this field is moving fast and it is thus important to afford scientists and engineers the opportunity to get updated by the best experts in the field. The present book draws together the latest developments in the fabrication technology of quantum structures, as well as a competent and extensive review of their fundamental properties and some remarkable applications. The book is based on a set of lectures that introduce different aspects of the basic knowledge available, it has a tutorial content and could be used as a textbook. Each aspect is reviewed, from elementary concepts up to the latest developments. Audience: Undergraduates and graduates in electrical engineering and physics schools. Also for active scientists and engineers, updating their knowledge and understanding of the frontiers of the technology.
