Parametric Interactions In One Dimensional Photonic Band Gap Structure

The aim of the work, is to study nonlinear parametric interactions, such as nonlinear frequency conversion and all-optical switching, in miniaturized photonic band gap materials. In particular, we wish to address highly efficient chi(sup 2) and chi(sup 3) processes in the short- wavelength range (less than 0.4 micrometers) to far (8-12 micrometers) IR regions of the electromagnetic spectrum near the photonic band edge of one-dimensional photonic crystals. The work is performed in collaboration with the group of Dr. C. Bowden, Weapons Science Directorate, Missile Research Development & Engineering Center, U.S. Army Aviation and Missile Command, Redstone Arsenal, AL 35898-5000. According to the previous reports related to the first 9 months of the contract, the work has been performed and continued following different activities, as described in technical report.

Since it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic band-gap materials and their use in controlling the propagation of light. This newly expanded and revised edition covers the latest developments in the field, providing the most up-to-date, concise, and comprehensive book available on these novel materials and their applications. Starting from Maxwell's equations and Fourier analysis, the authors develop the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory. They then investigate the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions. This new edition includes entirely new chapters describing important hybrid structures that use band gaps or periodicity only in some directions: periodic waveguides, photonic-crystal slabs, and photonic-crystal fibers. The authors demonstrate how the capabilities of photonic crystals to localize light can be put to work in devices such as filters and splitters. A new appendix provides an overview of computational methods for electromagnetism. Existing chapters have been considerably updated and expanded to include many new three-dimensional photonic crystals, an extensive tutorial on device design using temporal coupled-mode theory, discussions of diffraction and refraction at crystal interfaces, and more. Richly illustrated and accessibly written, Photonic Crystals is an indispensable resource for students and researchers. Extensively revised and expanded Features improved graphics throughout Includes new chapters on photonic-crystal fibers and combined index-and band-gap-guiding Provides an introduction to coupled-mode theory as a powerful tool for device design Covers many new topics, including omnidirectional reflection, anomalous refraction and diffraction, computational photonics, and much more.

This new edition features numerous updates and additions. Especially 4 new chapters on Fiber Optics, Integrated Optics, Frequency Combs and Interferometry reflect the changes since the first edition. In addition, major complete updates for the chapters: Optical Materials and Their Properties, Optical Detectors, Nanooptics, and Optics far Beyond the Diffraction Limit. Features Contains over 1000 two-color illustrations. Includes over 120 comprehensive tables with properties of optical materials and light sources. Emphasizes physical concepts over extensive mathematical derivations. Chapters with summaries, detailed index Delivers a wealth of up-to-date references.

Nonlinear optical phenomena can be exploited in advanced devices for transport, processing, and storage of information. These are needed as the present-day approach - mainly using on electron-based technology - faces the challenges of increasing demand on bandwidth and processing speed. A key role in the development of nonlinear devices is the availability of novel materials with the required nonlinear optical properties. With such materials, scientific creativity and careful design, promising concepts have been developed resulting in the demonstration of devices. This book contains the proceedings of NOIS 2000 (Nonlinear Optics for the Information Society) Annual Meeting of the COST Action P2, held at the University of Twente, in Enschede, The Netherlands, on 26-27 October, 2000. It comprises a selection of the presentations at the meeting, reporting state-of-the-art research and developments in the field of applications of nonlinear phenomena in information technology.

Photonic band gap crystals offer unique ways to tailor light and the propagation of electromagnetic waves. In analogy to electrons in a crystal, EM waves propagating in a structure with a periodically-modulated dielectric constant are organized into photonic bands separated by gaps in which propagating states are forbidden. Proposed applications of such photonic band gap crystals, operating at frequencies from microwave to optical, include zero- threshold lasers, low-loss resonators and cavities, and efficient microwave antennas. Spontaneous emission is suppressed for photons in the photonic band gap, offering novel approaches to manipulating the EM field and creating high-efficiency light-emitting structures. Photonic Band Gap Materials identifies three most promising areas of research. The first is materials fabrication, involving the creation of high quality, low loss, periodic dielectric structures. The smallest photonic crystals yet fabricated have been made by machining Si wafers along (110), and some have lattice constants as small as 500 microns. The second area is in applications. Possible applications presented are microwave mirrors, directional antennas, resonators (especially in the 2 GHz region), filters, waveguides, Y splitters, and resonant microcavities. The third area covers fundamentally new physical phenomena in condensed matter physics and quantum optics. An excellent review of recent development, covering theoretical, experimental and applied aspects. Interesting and stimulating reading for active researchers, as well as a useful reference for non-specialists.
