In spite of the increasing importance of microcavities, device physics or the observable phenomena in optical microcavities such as enhanced or inhibited spontaneous emission and its relation with the laser oscillation has not been systematically well-described-until now. Spontaneous Emission and Laser Oscillation in Microcavities presents the basics of optical microcavities. The volume is divided into ten chapters, each written by respected authorities in their areas. The book surveys several methods describing free space spontaneous emission and discusses changes in the feature due to the presence of a cavity. The effect of dephasing of vacuum fields on spontaneous emission in a microcavity and the effects of atomic broadening on spontaneous emission in an optical microcavity are examined. The book details the splitting in transmission peaks of planar microcavities containing semiconductor quantum wells. A simple but useful way to consider the change in the spontaneous emission rate from the viewpoint of mode density alteration by wavelength-sized cavities is provided. Authors also discuss the spontaneous emission in dielectric planar microcavities. Spontaneous emission in microcavity surface emitting lasers is covered, as are the effects of electron confinement in semiconductor quantum wells, wires, and boxes also given. The volume extends the controlling spontaneous emission phenomenon to laser oscillation. Starting from the Fermi golden rule, the microcavity laser rate equations are derived, and the oscillation characteristics are analyzed. Recent progress in optical microcavity experiments is summarized, and the applicability in massively optical parallel processing systems and demands for the device performance are explored. This volume is extremely useful as a textbook for graduate and postgraduate students and works well as a unique reference for researchers beginning to study in the field.

An understanding of spontaneous emission processes within microcavities is crucial in addressing the need to make tomorrow's microlasers more efficient. One approach to improving the device efficiency is to reduce the threshold input energy at which lasing begins to occur. It has been suggested that the threshold in a microcavity laser can be decreased by increasing the fraction of spontaneous emission into the lasing mode, this can be accomplished by preferentially coupling the gain medium of the laser to the electromagnetic cavity mode of interest. It therefore becomes necessary to understand the mechanism by which this coupling takes place. This research develops a fully quantum mechanical description of the interaction between a gain medium medeled as a two level atom and a multimode electromagnetic field in a microcavity. Atomic transition probabilities are computed for systems in which the atom couples through a single photon process to electromagnetic cavity modes which range in number from two to 2000. Calculations performed for cavities with widely spaced modes demonstrate that atoms exhibit Jaynes Cummings behavior when closely tuned to one mode. Detuning of the atom from the mode inhibits the exchange of energy, while increasing the strength of the coupling to the mode amplifies this exchange. Two level systems strongly coupled to many closely spaced modes exhibit spontaneous emission rates characteristic of an atom in free space.

A semiconductor interface is the contact between the semiconductor itself and a metal. The interface is a site of change, and it is imperative to ensure that the semiconducting material is sealed at this point to maintain its reliability. This book examines various aspects of interfaces, showing how they can affect microstructures and devices such as infrared photodetectors (as used in nightsights) and blue diode lasers. It presents various techniques for examining different types of semiconductor material and suggests future potential commercial applications for different semiconductor devices. Written by experts in their fields and focusing on metallic semiconductors (Cadmium Telluride and related compounds), this comprehensive overview of recent developments is an essential reference for those working in the semiconductor industry and provides a concise and comprehensive introduction to those new to the field.

The field of nonlinear optics developed gradually with the invention of lasers. After the discovery of second-harmonic generation in quartz, many other interesting nonlinear optical processes were rapidly discovered. Simultaneously theoretical programmes for the understanding of nonlinear optical phenomena were stimulated in accordance to develop structure-property relationships. In the beginning, research advances were made on inorganic ferroelectric materials followed by semiconductors. In the 1970's, the importance of organic materials was realised because of their nonlinear optical responses, fast optical response, high laser damage thresholds, architectural flexibility, and ease of fabrication. At present materials can be classified into three categories - inorganic ferroelectrics, semiconductors, and organic materials. Advances have also been made in quantum chemistry approaches to investigate nonlinear optical susceptibilities and in the development of novel nonlinear optical devices. Generally, inorganic and organic nonlinear optical materials and their related optical processes are reported in separate meetings. This book collects for the first time papers covering the recent developments and areas of present research in the field of nonlinear optical materials.

The optical properties of semiconductors have played an important role since the identification of semiconductors as "small" bandgap materials in the thinies, due both to their fundamental interest as a class of solids baving specific optical propenies and to their many important applications. On the former aspect we can cite the fundamental edge absorption and its assignment to direct or indirect transitions, many-body effects as revealed by exciton formation and photoconductivity. On the latter aspect, large-scale applications sucb as LEDs and lasers, photovoltaic converters, photodetectors, electro-optics and non-linear optic devices, come to mind. The eighties saw a revitalization of the whole field due to the advent of heterostructures of lower-dimensionality, mainly two-dimensional quantum wells, which through their enhanced photon-matter interaction yielded new devices with unsurpassed performance. Although many of the basic phenomena were evidenced through the seventies, it was this impact on applications which in turn led to such a massive investment in fabrication tools, thanks to which many new structures and materials were studied, yielding funher advances in fundamental physics.
