The 1990 International Topical Meeting on Photonic Switching was held April 12-14, 1990, in Kobe, Japan, in conjunction with the 1990 International Meet- ing on Optical Computing. It was sponsored by the Institute of Electronics, Information and Communication Engineers in cooperation with the IEEE Lasers and Electro-Optics Society, the Optical Society of America, and the Japan So- ciety of Applied Physics. The attendance was in excess of 340 persons, with 18 countries represented - a testimony to the current international interest in photonic switching. This book contains expanded and more...

Single-electron tunneling (SET) and related phenomena have recently come to be considered as "hot topics." This also became apparent when we organized the 4th International Conference on Superconducting and Quantum Effect Devices and Their Applications, SQUID'91, which was held June 18-21, 1991, in Berlin, Germany. Impressed by the number of contributions dedicated to the new physics of ultrasmall devices, we deemed it appropriate to devote this volume of the Springer Series in Electronics and Photonics to these specialized proceedings. The other contributions presented at SQUID'91, which are...

Over the last two decades, the search for a compact, high-power semiconductor source has produced many designs and concepts for monolithic diode-laser arrays and optical amplifiers. However, only a few design approaches have emerged with the potential for producing high-power, high-brightness monolithic sources. Although semiconductor-diode lasers are the most compact, highest gain and most efficient laser sources, challenges remain in developing structures that will produce high-quality, diffraction-limited output beams. This book presents and analyzes the results of work performed over the...

Silicon-Based Millimeter-Wave Devices describes field-theoretical methods for the design and analysis of planar waveguide structures and antennas. The principles and limitations of transit-time devices with different injection mechanisms are discussed, as are aspects of fabrication and characterization. The physical properties of silicon Schottky contacts and diodes are treated in a separate chapter. Two chapters cover the silicon/germanium devices: physics and RF properties of the heterobipolar transistor and quantum effect devices such as the resonant tunneling element are described....

In the past, a number of Satellite Conferences have been held in con nection with the International Conference on Physics of Semiconductors, covering selected fields of interest. In 1986, when the main conference was held in Stockholm, Sweden, new. phenomena had to be discussed: super lattices, hot 'electron phenomena and new device structures for high-speed applications. The aim was to select topics which would be of interest to physicists as well as to electronics engineers. Therefore a Satellite Con ference on H gh-Speed Electronics, Basic Physical Phenomena and Device Principles, was...

It has become almost a cliche to preface one's remarks about asymptotic tech niques with the statement that only a very few special problems in diffrac tion theory (be it electromagnetic, acoustic, elastic or other phenomena) are possessed of closed form solutions, but as with many cliches, this is because it is true. One only has to scan the literature to see the large amount of effort (both human and computer) expended to solve diffraction problems involving complicated geometries which do not permit such simplifications as separation of variables, It was a desire for techniques more...

Even elementary school students of today know that electronics can do fan tastic things. Electronic calculators make arithmetic easy. An electronic box connected to your TV set provides a wonderful array of games. Electronic boxes can translate languages Electronics has even changed watches from a pair of hands to a set of digits. Integrated circuit (IC) chips, which use transistors to store information in binary form and perform binary arithmetic, make all of this possible. In just a short twenty years, the field of inte grated circuits has progressed from chips containing several...

As Emile Jouguet remarked, "the shock wave flew off the tip of the pen of a theoretician for the first time" about a hundred years ago. The physics of shock waves has since grown into an independent branch of science closely linked with a wide range of research areas, from astrophysics and plasma physics to solid-state physics. Since the beginning, theoretical investiga tion has kept its leading role. The present book is devoted to actual problems of the theory of shock waves in gases and plasmas, that are of general interest to physicists. It con tains the results of studies on shock...

Noise in physical systems - as a consequence of the corpuscular nature of matter - conveys information about microscopic mechanisms determining the macroscopic behavior of the system. Besides being a source of information, noise also represents a source of annoying disturbances which affect information transMission along a physical system. Therefore, noise analysis can promote our insight into the behavior of a physical system, as well as our knowledge of the natural constraints imposed upon physical-information transmission channels and devices. In recent years the continuous scientific and...
