Available in PDF, EPUB and Kindle. Book excerpt: The dielectric microstructures act as ultrahigh Q factors optical cavities, which modify the spontaneous emission rates and alter the spatial distributions of the input and output radiation. The editors have selected leading scientists who have made seminal contributions in different aspects of optical processes in microcavities. Every attempt has been made to unify the underlying physics pertaining to microcavities of various shapes. This book begins with a chapter on the role of microcavity modes with additional chapters on how these microcavity modes affect the spontaneous and stimulated emission rates, enhance nonlinear optical processes, used in cavity-QED and chemical physics experiments, aid in single-molecule detection, influence the design of microdisk semiconductor lasers, and how deformed cavities can be treated with classical chaos theory.

Book excerpt: This final progress report summarizes research efforts in two areas: cavity QED of quantum dots and electromagnetically induced transparency (EIT) in GaAs quantum wells. Cavity QED studies are based on the development of a composite nanocrystal-microsphere system, in which CdSe/ZnS core/shell nanocrystals couple to whispering gallery modes (WGMs) in a fused silica microsphere. The composite microcavity system can feature a Q-factor as high as 108 and a nanocrystal decoherence rate as small as 3 microneV (0.75 GHz), indicating that the composite system can in principle reach the strong coupling regime of cavity QED. EIT studies have exploited the use of Coulomb interactions between excitons to induce and manipulate exciton spin coherence and biexciton coherence. These studies have led to the first experimental demonstration of EIT in inter-band optical transitions in semiconductors in A-type, cascaded, and V-type three-level systems.

This book was released on 2012-12-06 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical methods for investigating semiconductors and the theoretical description of optical processes have always been an important part of semiconductor physics. Only the emphasis placed on different materials changes with time. Here, a large number of papers are devoted to quantum dots, presenting the theory, spectroscopic investigation and methods of producing such structures. Another major part of the book reflects the growing interest in diluted semiconductors and II-IV nanosystems in general. There are also discussions of the fascinating field of photonic crystals. `Classical' low dimensional systems, such as GsAs/GaAlAs quantum wells and heterostructures, still make up a significant part of the results presented, and they also serve as model systems for new phenomena. New materials are being sought, and new experimental techniques are coming on stream, in particular the combination of different spectroscopic modalities.

This book was released on 2012-12-06 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: The control of optical modes in microcavities or in photonic bandgap (PBG) materials is coming of age! Although these ideas could have been developed some time ago, it is only recently that they have emerged, due to advances in both atomic physics and in fabrication techniques, be it on the high-quality dielectric mirrors required for high-finesse Fabry Perot resonators or in semiconductor multilayer deposition methods. Initially the principles of quantum electro-dynamics (QED) were demonstrated in elegant atomic physics experiments. Now solid-state implementations are being investigated, with several subtle differences from the atomic case such as those due to their continuum of electronic states or the near Boson nature of their elementary excitations, the exciton. Research into quantum optics brings us ever newer concepts with potential to improve system performance such as photon squeezing, quantum cryptography, reversible taps, photonic de Broglie waves and quantum computers. The possibility of implementing these ideas with solid-state systems gives us hope that some could indeed find their way to the market, demonstrating the continuing importance of basic research for applications, be it in a somewhat more focused way than in earlier times for funding.

This book was released on 2020-07-09 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Microcavities written by Alexey V. Kavokin and published by Oxford University Press. This book was released on 2017-04-28 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microcavities are semiconductor, metal, or dielectric structures providing optical confinement in one, two or three dimensions. At the end of the 20th century, microcavities have attracted attention due to the discovery of a strong exciton-light coupling regime allowing for the formation of superposition light-matter quasiparticles: exciton-polaritons. In the following century several remarkable effects have been discovered in microcavities, including the Bose-Einstein condensation of exciton-polaritons, polariton lasing, superfluidity, optical spin Hall and spin Meissner effects, amongst other discoveries. Currently, polariton devices exploiting the bosonic stimulation effects at room temperature are being developed by laboratories across the world. This book addresses the physics of microcavities: from classical to quantum optics, from a Boltzmann gas to a superfluid. It provides the theoretical background needed for understanding the complex phenomena in coupled light-matter systems, and it presents a broad overview of experimental progress in the physics of microcavities.

This book was released on 2006 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) This chapter explores the possibility of integrating NC-based microcavity lasers with microfluidic networks, thus providing the potential to dynamically tune the optical properties of the laser through interaction with different solvent environments on a miniaturized scale. Extension of the spectral window of NC-based gain media is discussed in Chapter 5, where extremely fast non-radiative Auger relaxation processes encountered in blue-emitting CdSe NCs may be circumvented by employing an alternative semiconductor NC, CdS/ZnS. Through judicious chemistry CdS/ZnS NCs may be uniformly incorporated into a sol-gel derived microcavity to provide room temperature lasing at blue wavelengths. Finally, our investigation into the optical physics of NCs in sol-gel derived microcavities is summarized in Chapter 6, which describes our observation of stimulated emission from multiexcitonic states in CdSe/ZnS NCs incorporated into a titania matrix. We employ transient photoluminescence to optically characterize the emission from these multiexcitonic states, which we attribute to 1P3/2-1Pc transitions. A DFB structure is introduced onto the CdSe/ZnS-titania composite to facilitate simultaneous lasing at two distinct wavelengths.
