Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2000 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonic band gap (PBG) crystals are artificially engineered periodic dielectric structures which exhibit frequency regions in which electromagnetic (EM) waves cannot propagate in certain directions. By using the "master mold" with desired features, an elastomeric mold of poly (dimethylsiloxane) (PDMS) with a relief structure on its surface was shaped. From these elastromeric molds, one-, two-, and multi-layer PBG samples were formed using microtransfer molding. The sol-gel solutions with the precursor of titanium diisopropoxide bis (2, 4-pentadionate)(TDBP), tetraethyl orthotitanate (TEOT) and titanium isopropoxide (TIPP) were infiltrated into the samples, respectively by spin coating. The infiltrated samples were sintered at 550°C. The sintered samples were characterized by optical microscopy, SEM and FTIR. Results show that the sintered samples experience large shrinkage (up to 40%) during heat treatment and therefore the structures had a low filling ration. The filling ratio can be enhanced by increasing the concentration of the precursor in the sol-gel. FTIR data showed that there were strong absorption peaks around 1500 cm−1 with a transmittance of 92.5% due to the existence of the first band gap of PBG structures. A sintered 4-layer sample was successfully obtained by infiltrating the sol of TDBP (26wt%) six times into the pattern through spin coating. It is likely that this approach can yield high quality three-dimensional PBG structures of Ti02.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Exploring for New Photonic Band Gap Structures written by Martin Maldovan and published by . This book was released on 2004 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the infinite set of possible photonic band gap structures there are no simple rules to serve as a guide in the search for optimal designs. The existence and characteristics of photonic band gaps depend on such factors as dielectric contrast, volume fraction, symmetry and connectivity of the dielectric structure. In this thesis a large set of photonic structures are developed to help understand the nature of the dependencies and provide a platform for easy fabrication of three-dimensional structures with large complete photonic band gaps. Two approaches for accessing new structures are examined. A systematic method based on crystallography to search for photonic band gap structures is established in this thesis. A search within the FCC space groups is undertaken resulting in the discovery of two new photonic band gap structures. Specific structures found in self-organizing systems, the single P, the single G, and single D structures, are shown to possess large photonic band gaps. Design guidelines to fabricate these structures by interference lithography are given. A layer-by-layer approximation of the single D structure amenable to fabrication by conventional semiconductor fabrication techniques is proposed. A second technique for obtaining photonic band gap structures with different topologies is based on the splitting of nodes in the diamond network. The realization of these structures using block copolymer self assembly and layer-by-layer lithographic technique are briefly examined.

This book was released on 2012-12-06 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at the NATO Advanced Study Institute (ASI) Photonic Crystals and Light Localization held at the Creta Maris Hotel in Limin Hersonissou, Crete, June 18-30, 2000. Photonic crystals offer unique ways to tailor light and the propagation of electromagnetic waves (EM). 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 where propagating states are forbidden. There have been proposals for novel applications ofthese photonic band gap (PBG) crystals, with operating frequencies ranging from microwave to the optical regime, that include zero threshold lasers, low-loss resonators and cavities, and efficient microwave antennas. Spontaneous emission, suppressed for photons in the photonic band gap, offers novel approaches to manipulate the EM field and create high-efficiency light-emitting structures. Innovative ways to manipulate light can have a profound iofluence on science and technology.
