Book excerpt: A light source is provided by a photonic crystal having an enhanced photonic density-of-states over a band of frequencies and wherein at least one of the dielectric materials of the photonic crystal has a complex dielectric constant, thereby producing enhanced light emission at the band of frequencies when the photonic crystal is heated. The dielectric material can be a metal, such as tungsten. The spectral properties of the light source can be easily tuned by modification of the photonic crystal structure and materials. The photonic crystal light source can be heated electrically or other heating means. The light source can further include additional photonic crystals that exhibit enhanced light emission at a different band of frequencies to provide for color mixing. The photonic crystal light source may have applications in optical telecommunications, information displays, energy conversion, sensors, and other optical applications.

Available in PDF, EPUB and Kindle. Book excerpt: The second volume of the book concerns the characterization approach of photonic crystals, photonic crystal lasers, photonic crystal waveguides and plasmonics including the introduction of innovative systems and materials. Photonic crystal materials promises to enable all-optical computer circuits and could also be used to make ultra low-power light sources. Researchers have studied lasers from microscopic cavities in photonic crystals that act as reflectors to intensify the collisions between photons and atoms that lead to lazing, but these lasers have been optically-pumped, meaning they are driven by other lasers. Moreover, the physical principles behind the phenomenon of slow light in photonic crystal waveguides, as well as their practical limitations, are discussed. This includes the nature of slow light propagation, its bandwidth limitation, coupling of modes and particular kind terminating photonic crystals with metal surfaces allowing to propagate in surface plasmon-polariton waves. The goal of the second volume is to provide an overview about the listed issues.

Available in PDF, EPUB and Kindle. Book excerpt: The role of dielectric mirrors is very important in optics. These are used for several purposes like imaging, fabricating laser cavities, and so on. The basis for the propagation of photons in dielectric mediums is the same as electrons in solid crystals. If the electrons can be diffracted by a periodic potential well, photons could also be equally well diffracted by a periodic modulation of the refractive index of the medium. This idea led to the development of many new artificial photonic materials and optical micro- and nanostructures. Since the mechanism of light guidance is essentially due to the microstructural features of the medium, a wide variety of photonic structures, e.g., photonic band-gap fibers in 1D and photonic band-gap crystals in 2D and 3D, can be realized. Photonic Crystals - A Glimpse of the Current Research Trends essentially highlights the recent developments in the arena of photonic crystal research. It is expected to be useful for expert as well as novice researchers; the former group of readers would be abreast of recent research advancements, whereas the latter group would benefit from grasping knowledge delivered by expert scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional photonic crystals (PC) have emerged as promising building blocks for integrated optics systems. Photonic crystal devices exploit defects, in an otherwise periodic lattice designed to exhibit a wide photonic bandgap (PBG), to form resonant microcavities or optical waveguides. The property of PC microcavities to enhance the source radiation into a desired mode while inhibiting other modes is particularly appealing for development of ultra-low threshold, single-mode lasers. In this final report we describe our work on the realization of photonic crystal vertically emitting microcavity light sources with electrical injection; edge emitting light sources integrated with PC-based waveguides; and PC-based resonant cavity photodiodes. We have realized the devices with GaAs- and lnP-based QW and QD heterostructures. We also present a theoretical investigation of the spontaneous emission characteristics of an ensemble of self-organized lnAs/GaAs QDs enclosed in the PC microcavity using guided modes as desired cavity modes. Combined with the molecular beam epitaxy and technology of self-organized QDs, photonic crystals can be further utilized to study single-dot lasing or for the observation of cavity electrodynamics (CQED) phenomena in semiconductor systems.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Renowned researchers from across the globe have contributed significant research inferences in this extensive book. Photonic crystals are described as the periodic optical nanostructures that are designed to affect the motion of photons in a similar way that periodicity of a semiconductor crystal affects the motion of electrons. This book introduces the concepts of innovative systems and materials to the readers. It provides comprehensive information regarding characterization approach of photonic crystal waveguides, photonic crystal lasers as well as plasmonics. Photonic crystal materials have the potential of enabling all-optical computer circuits and can also be utilized to design ultralow-power light sources. There is an in-depth account on lasers from microscopic cavities in photonic crystals acting as reflectors for intensifying the collisions between photons and atoms. This leads to lazing, but these lasers are optically-pumped, meaning that these lasers are themselves driven by other lasers. Furthermore, the physical principles behind the phenomenon of slow light in photonic crystal waveguides, as well as their practical limitations, have also been elucidated. The nature of slow light propagation, its bandwidth restraint, coupling of modes and specific kind terminating photonic crystals with metal surfaces enabling propagation in surface plasmon-polariton waves have also been described. The aim of this book is to provide an analysis of these mentioned issues to provide readers with a better understanding about photonic crystals.
Download or read book Photonic Crystals written by Jean-Michel Lourtioz and published by Springer Science & Business Media. This book was released on 2005 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Just like the periodical crystalline potential in solid-state crystals determines their properties for the conduction of electrons, the periodical structuring of photonic crystals leads to envisioning the possibility of achieving a control of the photon flux in dielectric and metallic materials. The use of photonic crystals as a cage for storing, filtering or guiding light at the wavelength scale thus paves the way to the realisation of optical and optoelectronic devices with ultimate properties and dimensions. This should contribute toward meeting the demands for a greater miniaturisation that the processing of an ever increasing number of data requires. Photonic Crystals intends to provide students and researchers from different fields with the theoretical background needed for modelling photonic crystals and their optical properties, while at the same time presenting the large variety of devices, from optics to microwaves, where photonic crystals have found applications. As such, it aims at building bridges between optics, electromagnetism and solid-state physics. This book was written by six specialists of nanophotonics, and was coordinated by Jean-Michel Lourtioz, head of the Institut d'A0/00lectronique Fondamentale in Orsay and coordinator of the French Research Network in Nanophotonics.

Book excerpt: This book comprehensively introduces photonic crystals and their applications including design and modeling characteristics. Photonic crystals are described as the periodic optical nanostructures that are designed to affect the motion of photons in a similar way that periodicity of a semiconductor crystal affects the motion of electrons. Photonic crystals are described as attractive optical materials for the purpose of manipulating and controlling the flow of light. Specifically, photonic crystals are of significant interest for basic as well as applied research, and two dimensional photonic crystals are being fast employed to commercial applications like micro electro-mechanical systems (MEMS), optical logic devices, and sensors. The first commercial products involving two-dimensionally periodic photonic crystals already exist in the form of photonic-crystal fibers, which employ a microscale structure to limit light with radically distinct features in comparison to traditional optical fiber for applications in guiding wavelengths and nonlinear devices.

Book excerpt: A photonic crystal is a periodic optical nanostructure that affects the motion of photons in much the same way that ionic lattices affect electrons in solids. Photonic crystals occur in nature in the form of structural coloration--and, in different forms, promise to be useful in a range of applications. Photonic crystals can, in principle, find uses wherever light must be manipulated. Existing applications include thin-film optics with coatings for lenses. Two-dimensional photoniccrystal fibers are used in nonlinear devices and to guide exotic wavelengths. Three-dimensional crystals may one day be used in optical computers.Photonic Crystals - Innovative Systems, Lasers and Waveguides concerns the characterization approach of photonic crystals, photonic crystal lasers, photonic crystal waveguides and plasmonics including the introduction of innovative systems and materials.
