Electromagnetic and mechanical oscillators are crucial in such diverse fields as electrical engineering, microwave technology, optical technology, and experimental physics. For example, such oscillators are the key elements in instruments for detecting extremely weak mechanical forces and electromagnetic signals are essential to highly stable standards of time and frequency. The central problem in developing such instruments is to construct oscillators that are as perfectly simple harmonic as possible; the largest obstacle is the oscillator's dissipation and the fluctuating forces associated with it. This book, first published in Russian in 1981 and updated with new data for this English edition, is a treatise on the sources of dissipation and other defects in mechanical and electromagnetic oscillators and on practical techniques for minimizing such defects. Written by a team of researchers from Moscow State University who are leading experts in the field, the book is a virtual encyclopedia of theoretical formulas, experimental techniques, and practical lore derived from twenty-five years of experience. Intended for the experimenter who wishes to construct near-perfect instrumentation, the book provides information on everything from the role of phonon-phonon scattering as a fundamental source of dissipation to the effectiveness of a thin film of pork fat in reducing the friction between a support wire and a mechanically oscillating sapphire crystal. The researchers that V. B. Braginsky has led since the mid-1960s are best known in the West for their contributions to the technology of gravitational-wave detection, their experimental search for quarks, their test of the equivalency principle, and their invention of new experimental techniques for high-precision measurement, including "quantum nondemolition movements." Here, for the first time, they provide a thorough overview of the practical knowledge and experimental methods that have earned them a worldwide reputation for ingenuity, talent, and successful technique.

Optoelectronics is a rapidly expanding field of research and development. In years to come, it is destined to play a primary role in the growing information industry. The basic philosophy behind the science and technology of optoelectronics is to create and develop photonic devices in which optical photons (light waves) instead of electronic carriers, are manipulated for the conventional task performed by microelectronics. Thanks to the availability of large bandwidth at optical frequencies, the development of cost-effective low-loss low-dispersion silica fibers for optical transmission, and the possibility of ultra-fast two-dimensional processing, the field of present-day microelectronics is moving steadily towards this new technology of optoelectronics and photonics.This volume presents reviews of different areas of optoelectronics written by international experts in the field, covering most of the topics of recent importance. It includes detailed discussions on semiconductor lasers and optical amplifiers; optical fiber transmission; photodetectors; optoelectronic and photonic integrated circuits; light-wave telecommunications; optical signal and image processing; optical computing; nonlinear and integrated optics; space-time Fourier optics; optical metrology and sensing and optical interconnects. All chapters are written in the style of a textbook containing tutorial sections which should be of great use to graduate students. The volume should serve as an excellent book for graduate level course on optoelectronics, modern optical engineering, and optical communications.
